Lesson 3- Level 1-2- Work Backwards- Homework

Pdf Summary

The document outlines Math Kangaroo Class Level 1-2 homework focused on the "Work Backwards" strategy. The exercises included in the lesson require students to find solutions by reversing operations or deducing information.<br /><br />1. The first problem asks for a number to be placed in a shaded cloud, which, after performing certain operations, results in 28. The solution given is 10.<br /><br />2. The second question involves placing a number in a square to achieve the result of 60 after performing predefined operations. The answer is 7.<br /><br />3. In a problem involving days of the week, it’s determined that today is Monday, and Tina’s birthday was five days ago. By working backwards, it is found that Tina's birthday was on a Wednesday.<br /><br />4. Another problem involves timing for a meeting at 1:15 p.m. For Linda, Mia, and Allison, each has different travel durations. By deducing who needs the most time, it is determined the person who needs the longest time, Mia, should leave at 12:30 p.m.<br /><br />5. A problem about cookies requires finding the number of sugar cookies Grandma made. It's given that there are a total of 45 cookies and adding 9 more sugar cookies would equate them to the chocolate chip cookies. The solution is that Grandma made 18 sugar cookies.<br /><br />6. Lastly, students are asked to create a similar problem to the one about cookies and solve it with an adult. Answers may vary for this task as students create their unique scenarios.<br /><br />The problems and solutions emphasize the strategy of working backwards, essential to solving many kinds of math problems efficiently.
