PDF Lesson 6- Level 3-4- Guess and Check- Presentation

Pdf Summary

Lesson 6 of the Math Kangaroo Class for Level 3-4 focuses on the problem-solving strategy of "Guessing and Checking." This method involves making an initial reasonable guess to tackle a problem and then checking if this guess meets the problem's conditions. If the initial guess is incorrect, it can still help in discarding wrong answers and providing insight to arrive at the correct solution. This approach is often referred to as "guess, check, and revise."<br /><br />The lesson includes several practical exercises, such as the Math Kangaroo questions from various years, which are designed to allow students to practice this strategy. For instance, students are asked to determine the digit hidden by stickers in a calculation, figure out how many squares need shading in a grid to balance shaded and unshaded areas, and decide which number will create the largest possible total in a sum.<br /><br />Students are encouraged to not assume that their first answer is correct but to explore all possibilities to find optimal solutions. The lesson highlights the importance of number sense and logical deduction in the guessing and checking process.<br /><br />In addition to problem-solving practice, students are given an exit ticket to reflect on when and how they can use the guessing and checking strategy in future problem-solving scenarios. A "Genius Hour" is also provided for students to create their problem-solving drafts.<br /><br />The lesson ends with optional homework suggesting taking the Math Kangaroo exam from 2018 and a bonus question where students need to order numbers while considering directional cues.<br /><br />Overall, this lesson aims to help students improve their problem-solving skills by employing a structured guessing and checking process to address complex mathematical challenges.
