Early Geometry Activities
Kindergarten students have been working on 2D and 3D shapes. Students will learn the basic properties of two and three-dimensional shapes along with their proper terminology such as solid, edge, face and corner will be introduced and used when referring to 3D shapes. These shapes include sphere, pyramid, cubes and cones. Other terms like flat, big, and small, will be used when referring to 2D shapes. Squares, rectangles, circles, hearts, hexagons, and the like, make up this category.
Why is Knowing About Shapes so Important?
By studying shapes, children learn skills that can be transferred outside the realm of mathematics, which is ultimately what we want our students to be able to do. For example, a child who is familiar with shapes and proficient in the other components in geometry can do the following:
- construct (e.g., Big flat blocks make a better foundation than tall narrow blocks).
- compare (e.g., This octagon looks a little like a circle).
- describe spatial relationships (e.g., The block is on top of the box).
- compose (e.g., Two squares can make a rectangle).
- decompose (e.g.,This pentagon can be taken apart in triangles).
