PDF Lesson 5 - Level 1-2- Organized List- Presentation

Pdf Summary

Lesson 5 of the Math Kangaroo Class for Level 1-2 focuses on the concept of making an organized list. The lesson emphasizes solving problems by organizing information into lists, which helps keep track of possibilities, avoid omissions, and reveal connections. <br /><br />The activities include:<br />1. **Brainstorming**: As a warm-up, students brainstorm things they can see in the sky.<br />2. **Number Hunts**: Students are tasked with finding how many numbers less than 100 contain a "3", and numbers less than 200 that are even and have a 5. Examples of organized lists by "Monkey" and "Kangaroo" are given.<br />3. **Problem Solving**: Several Math Kangaroo competition problems are included to practice making organized lists:<br />   - Determining the number of ways a cat can reach milk, considering specific movement rules.<br />   - Calculating the number of different ways Jake the Kangaroo can jump between circles.<br />   - Formulating numbers using certain digits while adhering to constraints, like all digits being different.<br />   - Finding combinations of numbers collected by squirrels, each with different quantities.<br /><br />Finally, the lesson wraps up by highlighting the usefulness of organizing thoughts into lists grouped into categories. It encourages students to arrange items sequentially (e.g., numerically) to ensure no possibilities are missed.<br /><br />A bonus question is introduced to extend critical thinking, asking students to identify how many three-digit numbers less than 150 are odd and have a 2 in the tens place. <br /><br />Overall, Lesson 5 aims to equip students with strategies for tackling a variety of mathematical problems by methodically organizing and exploring all potential solutions.
