PDF Level 3-4- Guess and check - Presentation

Pdf Summary

The document outlines a lesson plan for a Math Kangaroo Class aimed at students in Level 3-4 focused on the "Guessing and Checking" problem-solving strategy. It starts with a warm-up activity asking which four digits should be removed from the number 4921508 to achieve the smallest three-digit number. The lesson fits into a broader roadmap of problem-solving strategies that include finding patterns, drawing diagrams, and using logical reasoning, among others.<br /><br />The lesson emphasizes the "Guessing and Checking" method as a practical approach to solve problems by making an educated guess, checking it against the problem's conditions, and revising based on feedback. This strategy helps progressively eliminate wrong answers until the correct one is found.<br /><br />Throughout the lesson, various Math Kangaroo questions ranging from 2000 to 2020 are presented to engage students with different problem scenarios. These include puzzles about wrapping a measuring tape around a cylinder, calculating total payments equally distributed among boys, optimizing the sum of numbers on a grid, and determining the name of Rumpelstiltskin’s wife based on given conditions.<br /><br />The lesson also tackles a unique problem from the land of Funnyfeet, where group members must match shoes of the same size despite having feet of different sizes, and a separate bonus problem requiring logical deduction to complete an addition puzzle.<br /><br />The session concludes with a reflective wrap-up, where students discuss the effectiveness of the "Guessing and Checking" methodology, identify situations in which it could be particularly beneficial, and consider potential challenges and strategies to overcome them.
