PDF Lesson 3- Level 3-4- Make a List- Presentation

Pdf Summary

Lesson 3 of the Math Kangaroo Class for Level 3-4 focuses on the strategy of making an organized list to solve complex mathematical problems. The lesson emphasizes using lists to systematize information, avoid repetition, and thoroughly account for all possible scenarios, particularly in casework—a method of dividing a problem into distinct cases and solving each individually.<br /><br />The lesson includes practical examples that apply this strategy in solving various mathematical problems. For instance, it explores how many three-digit numbers can be created using given digits, counts small cubes with specific painting conditions, and determines arrangements of toys with specific adjacency requirements. Additionally, it tackles a problem involving page numbering in a book and calculating different path combinations between greenhouses.<br /><br />Students are encouraged to think critically about when to employ an organized list strategy, identifying which problems from the lesson benefited from this approach and considering potential challenges and solutions. Furthermore, they engage in Genius Hour, where they discuss problems they wish to create, enhancing creative and analytical skills.<br /><br />The lesson wraps up with a bonus question challenging students to calculate the minimum number of locks required to access a set number of coins within nested chests and boxes, reinforcing the list-making method's applicability in various scenarios. Optional homework includes practicing with a past Math Kangaroo exam.<br /><br />Ultimately, the lesson aims to enhance problem-solving skills through the organized list strategy, encouraging students to accurately process and approach complex situations mathematically.
