Understanding Shapes and Angles

In this Math Matters episode, Mrs. Hale teaches second graders to compare and contrast plain and solid shapes. Students gather materials, learn about vertices, and practice using math vocabulary. They explore shapes through drawing and counting, and reflect on their learning by comparing different figures. The lesson emphasizes communication skills and encourages students to use specific vocabulary to describe shapes.
