Okay, so welcome to Mexican Girl web lab. So today we will cover Canada and the time. So this web lab is for grade one and grade two. I know we do have several kindergartners. So let me introduce myself, okay. So let me share screen first. So my name is Ya He. So I am Mexican Girl instructor and also founder of AlphaSTEM and the Phoenix Chess Club. I graduated from Johns Hopkins University and now I mentor and advocate for gifted and STEM community such as Davidson Young Scholars, Johns Hopkins Citywide and County Gifted Association. I love math and I'm a passionate coach and led the team AlphaSTEM, won many national and international top awards for Math League, TJIMO, Purple Comet, Carderock Math Open and Math Olympiad and more. And also I want to introduce our TA, Harsh. Harsh, would you please introduce yourself? Yeah, hello everyone. My name is Harsh Akuneri. I'm a Math Kangaroo 2021 gold medalist receiving a perfect score. And so what I do is volunteer as a teacher assistant for Math Kangaroo classes. And a bit about my background information is I'm a sophomore in Livingston High School in New Jersey and I love math competitions and real world applied math and I hope others can gain and pursue the same passion I have for math. Okay. So I also want to learn more about you. So how about you? So Harsh, would you please share the poll, the two questions? Well, so we have many first-time kangaroo participants. So pretty much the same amount for first-grader and the second-grader. And we do have eight kindergartners. Okay, so let's start our class today. So what is Math Kangaroo? Since we have more, most kids are first-time attend Math Kangaroo competition. So I'd like to introduce. So Math Kangaroo is the math contest. There are 24 problems on the test. It's way different from the regular math problem we see in school. So it's much more fun, interesting. So for 24 questions, we divided into three different groups. One group, three points is easier. And another group is four points. And also we have five points. So each group, there are eight different problems. Which means we do need some strategies to finish them efficiently. And do our best. Okay, so let's have a brief look at some questions. For example, three points questions. So C, the first question here, you might be asked to count the number of animals you see. So can you see? So how many animals are here? So you can type your answer. You can type your answer via chat. Yeah, Coach Hush will trace the answer. How many animals you can see here? Well, we got different answers. Most answers, we got seven. We got three. We got five. We got four. Majority answer is four. Wow. So this is three points question. So let's see, what's the answer for this one? I think 90% got four. It's four, right? It's four, right? And we also have many answers for seven. What a pity. Four is not right. Seven is also wrong. So we have a few right answers. But three definitely is also wrong. So read the question carefully. You might ask to count the number of what animals? So is carrot animal? No. Is flower animal? Is apple animal? No. So read the question carefully. I know everybody can count, right? So it's easy. But you need to be very careful, right? So read the question carefully. What is the question asking you about? About animals, right? Now, how many animals? Since most kids, you do pay attention to the vocabulary. It's an animal. So you count this as four. But still, four is wrong. Why four is also wrong? Pay attention. There's a baby, right? So this is kangaroo. Mice kangaroo. Kangaroo. But inside the mummy kangaroo, there's a baby kangaroo, right? So instead of one, actually, we need to count two, right? So one, two, three, four, five. Yes. Although five, we have a least answer for five. But five is the right answer. Interesting, right? It's easy, but not as easy as you thought. You need to be very careful, OK? Even for three-point questions, sometimes it may be tricky. OK. For some questions, for example, the blocks, you cannot see them all. But you can use your imagination, right? So how many blocks here? How many blocks are here? So type your answer. This is easy. Yes, very good job. So far, oh, wow. So this is very good. Everybody have very good imagination, yeah. So it's 3D, even it's 3D. You can see, right? Yeah, we have 10, right? So you don't want to count them one by one. Definitely, you can't do that. But if you know, it's a 3 times 3, so which is 3 times 3. If you know, it's a 3 times 3, so which is 9. But on top, there's still 1, yeah, about, right? So 9 plus 1, we should have 10 blocks here. OK, so let's see some other questions. So all questions, we need different strategies. Sometimes we need a compilation for all kinds of different strategies. So what kind of strategies we can use in problem solving? So for example, always, we try to find a pattern, right? So pattern recognition. So for this one, the blocks, we cannot see all blocks, right? But we know the pattern. It's a 3 times 3, right? So pattern. And also, sometimes, we do need to draw a picture. It will help us to understand the question. And sometimes, we need to work backwards instead of forward. It will be much easier. And sometimes, there's so many information. We can easily mess up. So what should we do? We need to make an organized list to figure out a list of all kinds of probability, possibility. And always, always, always, we can guess the answer. And then double check. Use different approach. Use different way to check. Yeah, the answer. And a table and a chart as important as a picture. OK. So that's all kinds of strategies. Let's see how many strategies we can cover today. Among all these strategies, the method. How can we solve this kangaroo method? Number one, understand the problem. Read the problem carefully. Yeah. What's the problem asking about? If we're asking you about the animals, don't count the fruit. Don't count trees, flowers, right? And number two, plan. Make your plan how to solve the problem. Number three, carry your plan. So write down the solution step by step. Number four, look back and check and reflect. Does the answer make sense? Can there be a different answer? OK, so let's try to use all these methods and strategies. So before we start our problems, some basic information. Vocabulary. What's the minutes? We all know, right? So hours, hour hand, minute hand. Which one is longer? Hour hand or minute hand? Yes. Yes, very good. But some said hour hand. No, hour hand is shorter. The minute hand is longer. So see, we have two hands, the red one and the blue one. So blue one will be minute hand, longer hand. And shorter hand, the red one, will be hour hand. So there's a very important rule, OK? So when we tear a clock, always look at the hour hand first. So here, we see the hour hand. Yeah, it's pointing at 4, right? So then we can make a decision. The hour hand is close to 4, right? It's almost 4. And another thing is what? Another thing is the hour does not change until our clock is pointing right at the new number. So here, the hour hand is 4. This actually is easier, because we can tell it's 4 what? 4.07, right? 4.07, the clock. 4.07. But sometimes it's tricky, especially when it's, for example, 4.57. Sometimes you maybe got confused. It says it's so close to 5. Then maybe it's 5. No. Although it's very close to 5, but now it's not past 5. It still counters 4, the hour hand still counters 4. OK, so let's see. What time is this? So write down your answer, OK? So what time is this? Look carefully. So write in chat. What time is this? Oh, we got all different answers. Interesting. We got 5.35. We got 5.45. We got 6.45, 7.45, 7.50. Oh, interesting. So guys, before you write your answer, so let's observe. Is this a normal clock? No, no. So actually, it's not a regular clock, right? Because the number, it's wrong way, right? So we can see it's a kind of reflection. Oh, we can see, yeah, you see the clock in mirror, right? So it's not a, usually, clockwise is a star from 1, 2, 3, and this way, clockwise, right? But here, it's not a normal clock, right? 1, 2, 3, and this way, clockwise, right? But here, it turns the opposite way. It's counterclockwise. But no matter what, we check our hand first. So for our hand, it's a shorter hand, right? So you're pointing at which number? 5, right? Then we check the longer hand, minute hand, so which is pointing at 3. So the time, yes, is 5, 15. Yes. OK, so 5, 15. Let's see one year. So we know one year is 12 months, right? And how many days in a year? 365. But sometimes, it's 366, right? So sometimes, what does sometimes mean? It means leap year, right? Every four years, there's a leap year. So leap year, so we will have 366 days. OK, so another question. Since we have 60 seconds in a minute, 6 minutes in an hour, so how many seconds in an hour? So type your answer in chat. How many seconds in an hour? It's harder, right? Yes, oh my gosh, you guys are so good. Yes, exactly, 3,600. Yes. OK, good job. OK, so let's see other questions. This is easy. Which month has sometimes only 29 days? Which month has sometimes only 29 days? OK, so 98% give the same answer, February. And 1% give January, and also May, and also August. OK, so let's see. Which month, what's the keyword for this question? What's the keyword? The keyword here is sometimes, right? If we get rid of this word, which month has only 29 days? Then it will be different, right? Or if we change the only, we just ask, which month has 29 days? So which month has sometimes only 29 days? What does that mean? That means sometimes it's 29, sometimes it's not, right? So just as our previous question, so that's February. Why? It's a leap year, right? So every leap year, every four years, there's a leap year. So February will have one more day. So usually it's only 28 days, but leap year, February, has 29 days, right? OK, so let's pass this question, leap year. Second question. Anne's birthday was on Thursday, and her friend Eva's birthday was eight days earlier. So what day of the week was that? So think about it. Yeah. And we already got the answer. OK, so most answers are Wednesday. And also, the second popular answer is Friday, and then it's Thursday and Tuesday. Then let's check this question. OK, let's see. So Anne's birthday was on Thursday. We need to draw a picture now. So if we draw a picture, today is Anne's birthday, Thursday. And her friend Eva's birthday was eight days earlier. So let's go check backward. 1, 2, 3, 4, 5, 6, 7, 8. OK, then let's write down. This is Thursday. Then it's Wednesday, Tuesday, Monday, Sunday, Saturday, Friday, and Thursday, and Wednesday, right? So if we draw a picture, this question, very easy. Yeah, we can figure out. So the answer should be Wednesday, right? Wednesday. OK, so we use the first strategy, right? So draw a picture to help us to understand the question. OK, next one. So Anna visited her grandmother on Thursday, January 21, and invited her to her birthday party on February 3. What day of the week will the birthday party take place? Remember, January has 31 days. Okay, so this question is very straightforward. Yeah, majority answers are Thursday. Okay. Actually for ABCD. So we have all answers. It covers all choices. So let's see. Let's see this question. So, Anna visit her grandmother on Thursday, right, draw a picture, Sunday, Monday, Tuesday, Wednesday, Thursday, and Thursday is January 21st, and invite her to her birthday party on February 3rd. So let's, if we draw a picture, Thursday, Friday, Saturday, Sunday, and then start from Monday again, Tuesday, Wednesday, then we count 21. And if we familiar with the calendar. So, every seven days, you repeat right. So, basically, we can count by seven. So if a 21 locate a Thursday. Then, if it plus seven. So 28 must also be Thursday, right. So, and then, if we add a seven to 28, then we just continue. So 2930 31 first, second, third night. Indicate which which day of the week, Wednesday. Yeah, it seems the Thursday we got the most answer. So, see, if you draw a picture, it will be easier, much easier. Right. So the answer for this one is Wednesday. Okay, so next one. Next one, be very careful next one, because sometimes the question. Yeah, very tricky, even though you know how to do it, but there's still some information, maybe you didn't really understand that. So, let's see. The doctor gave a certain medicine to Ada. He gave her 60 pills and told her to take one pill each day. She began taking the pills on Monday. What day of the week, will it be when she takes the last pill. So, work on this one. So for previous question, we know if we draw a calendar, yeah, draw a picture, okay, so draw a calendar. So Monday, Tuesday, Wednesday, all the way to Sunday. And so she start on which day? On Monday, right? So on Monday, she begin, or the first day. She begin, or the first day. Then, what's the next day? For, what's the next day? So see, Monday, she started. And every seven day, repeat. But here, be very careful, okay? So Monday, we already count her the first day. It's not a day zero, it's day one. So if the first day is Monday, then if we count by seven, if we count by seven, so what does that mean? Monday is the first day, right? So the next Monday will be which day? The next Monday will be eighth day, right? Will be eighth day. So one plus seven equals eight. And then next Monday will be 15th, right? So in this way, so let's count. This give us number 16. We try to find the maximum, maximum number which can be counted by seven, right? So one plus seven equals eight, right? And which number can be divided by seven? Which number? 56, right? Then 56 will be what? Will be one day before Sunday. Will be one day before Monday. So 56, because 56 can be divided by seven. So 56 should be one day before Sunday. Why? Because this is one, two, three, four, five, six, seven. Sunday is the seventh day, right? Since Monday count as the first day. Okay, then 57 will be also on Monday, right? If we figure out 57 is here, then 60, 60 days will be very close, right? So we just count forward. 57, 58, 59, then 60, right? So the next day will be what? Will be Thursday. Let's see. Oh yeah, we do have a Friday and a Thursday. They're pretty much the same. So half students got Friday, half got Thursday. Yeah, so can you understand why Friday is wrong? If you just plus seven and find the multiple for seven, then you can easily get wrong. Why you get wrong? Because you forget to count Monday is already considered as the first day, right? Okay, so be very careful. Yeah, so whether the first day count, already counted as first day or you start from the second day. If we said in three days, then the first day we haven't counted yet in three days. So in first day, the second, and in three days, then it will be Thursday, right? But if we said we take medicine, start from Monday, and you take three days, then it's the first day, second day, then third day, right? So it's very easy to get wrong. Yeah, so anyway, just read the question carefully and draw a picture to help you understand the question. Next one. Next one. So you need to draw your own picture to make your own calendar, okay? So the first day of a certain month that has a 30 days is a Monday. So the question, how many Mondays does this month have? So think about this. Don't rush to give me answer, okay? So you need to draw a picture, make your own calendar. The first day of a certain month that has 30 days is a Monday. So how many information is here? It's the first day of month. This month have 30 days, and the first day of this month is Monday. So three informations. How to process this information? Okay, see, let's draw a picture, okay? So make our own calendar, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. And the first day of this month is Monday. Okay, and then we know, so every seven days, it go back to Monday. So when then plus seven, we got eight, plus seven, we got 15, plus seven, we got 22, plus seven, we got 29, right? And we know, because we have 30 days, so 29 is fine, we can't have 29 in that month, right? Okay, then how many Mondays does this month have? One, two, three, four, five. So we have five. Okay, very good. So 50, about more than 50, yeah, got the right answer. Yeah, yes, very good. So see, Monday, make your own calendar. Very efficient, very helpful, yeah, to help you solve this kind of problem. Next one. Eastern ET must have the clock, which shows exactly six o'clock. Which clock will he choose? Which one? Wow. Remember, shorter hand and a longer hand, which one count as the hour hand? Which one count as the minute hand? Since this is a six o'clock, right? So which means the hour hand should be pointing at six, while the minute hand should be pointing at 12, right? Or it can be zero. So 12 and a zero, yeah, it's the same for a clock. So which one is right? This one, wrong, minute hand, wrong. This one, wrong, minute hand, wrong. So the B and the C, which one is right? So majority kids get it right, very good. Yeah, it's C, because the shorter hand pointing at six. Yeah, very good. Okay, so what's the important rules? So let's review. So always look at the hour hand first, right? And the hour hand does not change until our clock is pointing right at the new number. Right? Okay, so keep in mind. Yeah. Next question. Math workshops start at 5 p.m. today. Alan was 15 minutes late for the workshop. What time did Alan come? So how to do this? This is an easy one. Read the question carefully, even though it's easy. But let me see. We already have 10 wrong answers. So, yeah. Okay, so this one we can quickly. What time is it? It's 5.15, right? So 5.15. Okay, so next question. The picture below shows a part of a train schedule. Right now, it's 8.45. Mr. Smith will go from Chicago to Indianapolis on the next train. The trip will take two hours and 45 minutes. What time will Mr. Smith arrive? What time? We have all different answers for this question. But it seems C is the most popular answer. But which one is right? So even though you finished this question, think again. Read the question carefully. Is there any information you missed? Or is there some hidden information? You didn't say clearly, but there is a certain clue you need to consider. OK, so Hush, will you please share the result for this question? OK, so for this one, I think most students choose C, 11, 15. And some choose D, 12 o'clock. And also some choose B, 9, 40. And some choose 1 o'clock. Let's work on this one. So the train schedule, it shows us when will the train leave, right? It gives us five different times. What does that mean? What does that mean? That means it's not 8.45. 8.45 is the time so Mr. Smith arrived, right? But it doesn't mean he can leave at that time, right? So the train has a specific schedule. So the schedule is here. 6.55? Oh no, it's too early. He cannot catch this one. So how about 8.30? No, he cannot catch that one, too, because it's 15 minutes before he arrived. The train already left, right? So he cannot catch this one. So which one Mr. Smith can catch? 11.15? Yes. 12.50? Yes. 9.15? Yes. These three, he can make. But read the question again. Mr. Smith want to go what on the next train? He don't want to wait two hours, one hour. He want to just leave as soon as possible. He want to just take the next train. So which one will be next train? Among three of them, only one is next train, right? So which one? 9.15, right? So this one is the one Mr. Smith take. Yeah, he will take, right? So 9.15, this is the train he will take. So instead of we just use this number plus the trip, how long it takes the trip. And definitely not this way, right? So we need to use the right one. The right one will be 9.15. OK, so the 9.15, we need to add two hours and 45 minutes. So we need to do this, right? OK, let's see. This is hour and hour. We add 9 plus 2 equals 11. And a minute plus minute, 15 minutes and 45 minutes. So total should be 60 minutes, right? So we never said it's 60 minutes. Whenever it's 60 minutes, it's equals to one hour, right? So 11.60 actually is 12 o'clock, right? So what's the right answer? Although 12 is not the most popular answer here, but it's right, 12. If you are not familiar with this way, so 9.15 plus 2, 45. And hour plus hour, minutes plus minutes. You can also use what way? You can also draw a picture, OK? So drawing a picture is always helpful, OK? So let's see. If you draw a timeline, this is 9.15. Then you can draw one hour, two hours. So then it will be 10.15, just one hour. Two hours, so then it will be 11.15, right? And it takes two hours and 45 minutes, right? So there should be another 45 minutes. Then 11.15 plus another 45 minutes equals what? Again, equals 12 o'clock, right? So equals 12 o'clock. So see, we use different ways. We can either use this calculation or we use this picture. Draw a picture of the timeline. But both ways, we get the same answer, 12 o'clock, right? So this question is interesting. Why? It's not only about the calculation. It's also about understanding, right? So read this question carefully. So figure out all the information, the clues, and use all of them. And sometimes you do need to go back and check, right? So any information you missed, and try to fix it by yourself. OK, so this is question eight. Question eight. OK, so see, plus two hours and 45 minutes. So you can also do this way. Since plus two hours and plus 45 minutes, you can also do a different way. Plus 45 minutes first. Plus 45 minutes, yeah, it's easier. And then plus two hours, right? So 9.15 plus 45 minutes first. Then you get 10 o'clock, right? 10 o'clock. So see? Then go to 10 o'clock. And then plus two hours, that's much easier. So 10 o'clock plus two hours, you get 12 o'clock, right? So the answer is 12 o'clock at night. 12 o'clock. Is there any information at night? No, it's just 8.45. But anyway, it's 12 o'clock. OK, so next question. Oh, think about this one. Think about. So take your time. Think about it. A certain play has two 45-minute parts and an intermission between them. The play started at 10.50 and ended at 12.40. How many minutes now was the intermission? So work on this one. Wow, so quick. I already got, again, all four choices. Yeah. So take your time. No rush to give answer. Draw a picture. So it's only time. Over 100 students gave the answers. So most answers are D, and the next one is A, and then we also have C and B. So which one is right? Which one is right? Again, draw a picture, okay? So a certain play has two 45-minute parts. Let's draw. This is a play. It has two 45-minute parts, 45, 45, okay, so 45 minutes, 45 minutes. And an intermission between them, so this is a break time. So the play started at 10.50, so it started at 10.50, and ended at 12.40, 12.40. So how many minutes now was the intermission? How many minutes now? So to solve this one, we need to figure out how long in between. To solve this one, number one, let's organize. Number one, we need to figure out how long from beginning to the end, right? How long? From 10.50 to 12.40, how long? Similar to the previous question, we have two ways, at least two ways to solve this one, right? First, we need to do the calculation, so 12.40, 12.40, minus 10.50, oh, it seems 40 is smaller than 50, not enough to minus, so we need to borrow, right? So where do we borrow from hour? So for one hour, we know it's 60 minutes, right? So how about we borrow one hour? So 12, borrow one hour, then 12 turn to be 11, right? But now, 60 minutes will add it to 40, right? So then it will be 100, right? So 12.40 turns to be 11, 100, 11 hours and 100 minutes, and then we can do the calculation. So 100 minus 50 equals 50 minutes. Now 11 hours minus 10 hours equals one hour. So then it should be what? It should be one, is this right? One hour and 50 minutes, right? One hour and 50 minutes. So this is how long from beginning to the end, and we know the place, there's two parts of 45 minutes and 45 minutes, so we add them all. So it's 45 minutes plus 45 minutes, 90 minutes, right? 90 minutes actually equals what? Equals one hour and 30 minutes, right? So 90 minutes equals one hour, 30 minutes, right? So we minus, so one hour for 50 minutes minus one hour, 30 minutes, how many minutes we get? We get 20 minutes, right? So this break time is 20 minutes actually, right? So 45 plus 20 plus 45, so we just check, okay, double check. So it will be 190 plus 20 equals 110. This is how long, right? Okay, so this is one way we solve this kind of problem, but if this way is too... You don't feel comfortable to solve like this way, so you can always change other way to solve this kind of problem. So let's see what other way we can solve it. This other way, again, draw a picture, right? Draw a picture, let's see. So from 10 to number one, still number one, first thing we need to figure out how long it lasts from beginning to the end, how long it lasts. So instead of we use the calculation, one minus one, we can do the timeline. Okay, so from 10.50 to 12.40, so let's see, because 10.40 is close to 10 minutes to 11, right? So it's 10 minutes to 11 o'clock, and 11 to 12, one hour, to one, another one hour, to two, another one hour, right? So it's... Oh, this is 12, 12.40, right, 12.40. So here, actually, 10.50, 10 minutes to 11. So see, so raise the question again, then if there's any problem, we fix it. So start from 10.50, after 10 minutes, it will be 11 o'clock, right? So 11, and then after one hour is 12, and then it's 40 minutes. So this is a 10 minutes, this is a 40 minutes, this is a 10 minutes, this is one hour. So how long it takes? Same thing, right? So one hour and 15 minutes, one hour and 15 minutes, also one hour and 15 minutes equals what? Equals one, one, zero minutes, right, because one hour equals 16 minutes. So we use different ways, yeah, but the same solution. Okay, so also you can see, from 10.50 to 12.40, so total one hour and 15 minutes, and first half 45 minutes, last half 45 minutes, in between 20 minutes. So the answer should be 20. Okay, so this kind of time problem can be complicated, so it's always very helpful, so you draw your picture, okay? So last question, so read the question first. So read by yourself, okay? And try to solve. Okay, we already have more than 100 answers. Most answer is A and the second popular answer is B. And also we have C and D's. So which one is the right answer? Let's work on this one. Again, draw a picture. Okay, so if she lives at 4 p.m., she needs an hour to get to a shopping center. If she lives at 4, then she gets there half an hour after the store closes. We don't know when the store is open, when the store is closed. So how about this is closed, this is open. So if she starts to live at 4, then when she can get there? At 5, right? At 5 o'clock she will get there. But when she gets there, she's half an hour after the store closes. Oh, so 5 o'clock, the store already closed. So which means, what time is the store closed? At 4.30, right? Half an hour before she arrived. 4.30 it will close, the store will be closed. And if she lives at 8 a.m., remember, we always need to add one hour, so she needs one hour to get there. So if she lives at 8 a.m., so she gets there, which means 9 o'clock she gets there, it's half an hour before. Oh, so at 9 o'clock, if she gets there, the store hasn't opened yet. So what time does the store open? It's 9.30, right? So at 9.30, the store starts to open. Okay, so we figured out the store hours. So 9.30 a.m., it opens. 4.30, it closes. Okay, so then what's your answer? A is the right answer, right? Yes, A is the right answer. So if you draw a picture, yeah, it will show very clearly, right, what time it closed, what time it opened. And also there's information you still need, you cannot just use 8 o'clock, yeah, to plus or minus the 30 minutes. Always remember, it takes an hour to get to the shopping center first. Okay, so this is the 10 questions we covered today. And since we have a little bit more time, one hour more time, so how about I give you guys a challenge question. So you guys are ready for a challenge question? Okay, so this is interesting, but this is hard. Okay, so just for fun. So since we're already in the clock, we're already in Canada today. So let me share the question. The question, okay, so where's the question? Okay, can you see my screen? I also make up a story. The story is there's an emergency treehouse, there's something happened for Mr. Rabbit, his house was stolen and very precious gold coins were stolen. And there's no clue when did it happen. But the only thing we can see in the emergency treehouse is one piece of a clock, the clock is broken, but it's frozen, time is frozen. The only thing we can see is this. See, which one is our hand? I think you should share your screen. I'm not sure sharing. Okay, let me share screen. Okay, let me share screen. Okay, so can you see my screen now? Can you see my screen now? So this is the only thing you can see. There's a red hand pointing to the minute, our hand, and our hand and the minute hand, and it's pointing, both hand pointing at, see, this is two points, right, for clock, they're always points, right? And can you figure out what time it happened? So you are a detector, so you need to figure out the clue, what time it happened? No, any other clue, only broken, one piece of broken watch, clock. This is only one piece. So think about this one. So we don't have time to cover this, but it looks easy, but actually, the more you think, the harder it can be, but it's very interesting. Yeah, play with your clock at home and try to figure out this question. Yeah. Okay, I think that's all for today. So this question challenge one, so you can think at home and you can use clock to demonstrate. Yeah, and that's all for today. Hush. So thank you so much, everybody. So join our webinar today. Yeah, thank you. Yeah, there is a survey, so when you finish, so thank you for finishing survey as well. Yeah, if you have come up with an idea how to solve this one, you can always, yeah, so send an email to me on hush at yeah, at macekangaroo.org. Yeah, for your answer. Yeah, enjoy. Yeah, enjoy Macekangaroo, the thinking fun. Bye. Bye, everyone.
