PDF Lesson 4- Level 5-6 - Ratio & Proportion- Teachers file

Pdf Summary

This document outlines a lesson plan for teaching ratios and proportions to students participating in a Math Kangaroo competition at levels 5-6. The lesson plan consists of various segments including a warm-up exercise, instruction on key ideas, and a series of problem-solving sessions. The session is structured to include a 5-minute warm-up involving calculating speed, 5 minutes to go over key instructional ideas, 28 minutes spent on solving multiple problems, a potential breakout session for 12 minutes, and a 10-minute wrap-up review.<br /><br />Key mathematical concepts covered include understanding and writing ratios in different notations (words, fractional, and colon), solving proportions using the cross multiplication technique, and practical applications of these concepts in solving real-world problems drawn from Math Kangaroo past competitions.<br /><br />Problems are discussed in detail, providing solutions with clear rationale. For instance, a problem about a motorcyclist calculates the distance covered at a constant speed, demonstrating doubling of distance when time is doubled. A common question asks how many times faster the minute hand of a clock moves than the hour hand, though the document doesn't specify the answer directly.<br /><br />Solutions to Math Kangaroo problems cover a wide array of scenarios like calculating distances, solving competitions problems, evaluating areas of geometric figures, understanding relative weights of animals, and deciding the dimension changes in geometric shapes.<br /><br />The lesson concludes by emphasizing the importance of understanding ratios and proportions and provides optional homework for further practice. It serves as a comprehensive guide for students to build a strong foundation in these mathematical concepts, which are critical for solving related Math Kangaroo problems.
