PDF Lesson 7 - Level 1-2- Guess and Check- Presentation

Pdf Summary

Lesson 7 of the Math Kangaroo Class for levels 1-2 focuses on the "Guess and Check" strategy. This method is designed to help students tackle mathematical problems by making educated guesses and checking if those guesses meet certain conditions. The strategy is sometimes referred to as "Try and Revise," where the initial solution is adjusted if it does not meet the problem's requirements.<br /><br />The lesson provides a variety of warm-up exercises to engage the students. For example, they are asked to guess numbers based on specific attributes such as being odd, having two digits, and summing the digits to a given number. These exercises encourage flexible thinking and familiarity with number properties.<br /><br />The lesson also includes several Math Kangaroo competition problems from past years, challenging students to apply the Guess and Check strategy to solve them. These problems involve determining specific numbers that satisfy various conditions, such as balancing sums or fitting within certain constraints.<br /><br />In the wrap-up, it is emphasized that "Guess and Check" can be particularly useful for solving certain types of Math Kangaroo problems. Students are encouraged to iterate their guesses, refine them based on the given conditions, and keep trying until they find the solution. Bonus questions are provided to further challenge the students' problem-solving abilities, asking them to arrange numbers and operations in ways that satisfy specific mathematical criteria.<br /><br />Overall, this lesson introduces students to an effective problem-solving technique, helping them to approach complex problems methodically. It combines direct instruction with hands-on practice and past competition problems to reinforce learning and build confidence in mathematical reasoning.
