PDF Lesson 9 Level 7-8 Logic-Class Student

Pdf Summary

The provided document outlines a Math Kangaroo preparation course for Level 7-8 students, focusing on logic problems and strategies to solve them. Key contents and topics in the course include:<br /><br />1. **Warm-up Problem Example**: A classic problem involving picking colored balls from a bag demonstrates introductory logic challenges.<br /><br />2. **Course Structure**: The course includes various mathematical and logical subjects such as Calculations with Rational Numbers, Algebraic Thinking, Geometry, Combinatorics, and Logic among others.<br /><br />3. **Problem-Solving Strategies**: A four-step strategy is recommended for solving problems, which includes understanding the problem, planning a solution, executing the plan, and reviewing the answer.<br /><br />4. **Introduction to Logic**: Logic is described as reasoning to obtain results, emphasizing deductive reasoning and the Pigeonhole Principle, which is used to solve problems by ensuring certain outcomes.<br /><br />5. **Specific Logic Topics**: <br />   - Cryptarithms: Problems where letters are substituted for numbers.<br />   - Knights and Knaves: Classic problems where some characters always tell the truth while others always lie.<br />   - Logic puzzles: Requires pairing items accurately based on given clues.<br /><br />6. **Sample Problems**: A variety of problems from past Math Kangaroo exams are presented, including those involving cryptarithms, determining the presence of a lion based on contradictory clues, and problems involving Knights and Knaves.<br /><br />7. **Advanced Challenges**: These include unique scenarios such as identifying eating patterns to solve deductive problems or understanding the dynamics in a room with multiple truth-tellers and liars.<br /><br />8. **Genius Hour Project**: Encourages students to apply what they've learned to create presentations solving selected logic problems, reinforcing comprehension through teaching.<br /><br />9. **Conclusion and Tips**: Emphasizes the importance of understanding key points, organizing information with charts or diagrams, and using strategies like proof by contradiction to tackle wordy logic problems effectively.
