Comparing Shapes and Their Properties

This lesson focuses on comparing two-dimensional shapes using the concepts of 'alike' and 'different'. It begins with a comparison of a dog and an elephant to illustrate these concepts. The lesson then moves on to sorting shapes based on the number of vertices and sides, providing examples with triangles, squares, rectangles, circles, and hexagons. The lesson concludes with a preview of the next lesson, which will involve problem-solving and drawing shapes.
