Understanding Coordinate Grids and Transformations

In this lesson, students learn about using coordinate grids to create and transform sailboat shapes. The teacher guides students through plotting coordinates to form an original sailboat and then explores transformations by doubling and tripling coordinates to create new versions. The lesson concludes with interactive games like Battleship and Hidden Treasure to reinforce coordinate grid concepts.

What is the main topic of Everyday Math Lesson 4.8?
