Pdf Summary

Lesson 3 of the Math Kangaroo Class for Levels 1-2 centers on the strategy of working backwards to solve problems. This lesson introduces students to reversing operations, such as using addition instead of subtraction or division instead of multiplication, to find the initial values when the final answer is known. The lesson plan includes a warm-up, several problem-solving activities, and a wrap-up review, all aimed at reinforcing this strategy.<br /><br />Key components of the lesson include:<br /><br />1. **Four-Step Method:** Although not formally introduced in this lesson, students are encouraged to understand problems, plan, carry out the solution, and reflect on their answers.<br /><br />2. **Problem Activities:** Several problems are given where students must work backwards to find solutions. For instance, discovering who caught a fish, determining the original number needed before certain operations, or figuring out past events based on the current day.<br /><br />3. **Breakout Room Discussions:** Students are given opportunities to collaborate in breakout rooms to discuss and solve problems, fostering teamwork and alternative solution approaches.<br /><br />4. **Reinforcement through Examples:** Problems like the mouse reaching cheese or Tom’s birthday are used to illustrate the concept. Students learn to figure out which gates to close in a maze or calculate the weekday of past events by counting backwards from the present.<br /><br />5. **Practical Applications:** The lesson includes real-world analogies like John's and Olivia's sweet exchange to help solidify the students' understanding of working backwards.<br /><br />The approach enhances comprehension through interactive problem-solving while encouraging students to consistently apply reverse thinking in situations where they know the outcome but need to deduce initial conditions.
