PDF Level 3-4- Guess and check - Teacher file

Pdf Summary

The document outlines a Math Kangaroo class for levels 3-4, focusing on "Guessing and Checking" as a problem-solving strategy. The class involves several components: a warm-up, instruction, problem-solving, and wrap-up over a 60-minute lesson.<br /><br />The lesson introduces the 4-step problem-solving strategy: understanding the problem, planning a solution, carrying out the plan, and checking the result. Through this framework, students learn to use guessing and checking effectively to solve problems by making an initial guess, verifying its accuracy, and revising as needed.<br /><br />Key exercises discussed include determining which digits to remove from a number to achieve the smallest possible figure, solving measurement tape problems, understanding how pricing can be evenly divided among buyers, and logical deduction challenges involving identifications and arrangements of items and people.<br /><br />Vocabulary covered in the lesson includes terms like "row," "column," "cylinder," and "sum." These terms are meant to enhance understanding during problem-solving exercises.<br /><br />The document also details specific examples from past Math Kangaroo contests with answers and explanations, providing a basis for applying the guessing and checking strategy. It guides students on how to use the strategy when other methods aren't apparent, emphasizing its usefulness for gaining insights and eliminating incorrect options.<br /><br />During wrap-up, students reflect on the problems where guessing and checking were most beneficial and how they can apply this strategy in future scenarios. The lesson encourages sharing thoughts on overcoming challenges and using reasoning to solve problems more efficiently. Additionally, students are encouraged to present their thoughts during the "Genius Hour," fostering a collaborative and reflective learning environment. Overall, the lesson promotes a structured approach to problem-solving that combines intuition and systematic verification.
