3rd Grade Math - 2D and 3D Shapes

Updated: Jan 20

This post explains and gives practice opportunities related to TEKS 3.6A:

classify and sort two- and three-dimensional figures, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language


In third grade, students use increasingly complex vocabulary to classify and sort shapes. Here's a video about 2D shapes.

And here's a separate video about 3D solids.

Finally, we look at what makes prisms unique.
