PDF Lesson 3-B Level 7-8 Algebraic Thinking-class teacher

Pdf Summary

This document outlines a Math Kangaroo preparation lesson focused on Algebraic Thinking for Levels 7-8. The structure of the lesson includes various segments with specific timings, starting with a 5-minute warm-up problem and progressing through instruction on Algebraic Thinking, problem-solving practice, a potential Genius Hour discussion, and a wrap-up session.<br /><br />The lesson begins with an introduction to algebraic concepts, such as the use of variables to solve equations and combine like terms. Key strategies for problem-solving are taught, including understanding the problem, planning the solution, executing the plan, and reflecting on the answer for accuracy.<br /><br />Sample problems from past Math Kangaroo contests are included, covering a range of algebraic applications. Problems discussed include determining the cost of chocolate bars, calculating volumes of combined objects, interpreting sums in matrices, and solving logical or numerical puzzles, like calculating alien tentacles or finding candy distributions. Each problem is followed by an explanation of the solution process.<br /><br />The lesson highlights a 4-step problem-solving strategy and encourages students to apply algebraic thinking through various mathematical tasks emphasizing calculation, logical reasoning, and pattern recognition. Topics to be covered in the broader course include Rational Numbers, Number Theory, Algebraic Thinking, Work, Rate, and Ratio, among others.<br /><br />The document also introduces the Genius Hour project, encouraging students to explore a math-related hobby or interest through a problem-solving lens. Students are expected to develop a presentation of their project, explaining the problem, solution process, and underlying mathematical concepts.<br /><br />Finally, the lesson wraps up by encouraging students to practice independently, reflect on interesting problems, and identify techniques used during problem-solving. The aim is to build confidence and improve algebraic reasoning skills in students preparing for Math Kangaroo competitions.
