Challenge Friday: Geometry 3D Shapes


The kids have been studying geometry in math. The kids have to know the names of solid figures, such as sphere, pyramid, cube, cylinder, cone, and rectangular prism. For each shape they have to know how many faces, edges, and vertices it has. So for Challenge Friday, our mission this week was to make one of the solid figures out of Legos and then write about it, describing it by its geometric properties. After making one, they could make another if they had time.

Although cubes, pyramids, and rectangular prisms were very popular, some kids found very creative ways to make cylinders, cones, and even spheres! We met in a share circle after every student had had a chance to make at least one shape. In the share circle, they described their shape by how many faces, vertices, and edges it had, and the other kids had to guess what shape it was. Once they guessed the correct shape, the student revealed the shape they made.

I took a picture of each shape that the kids made and then they glued the picture in their notebooks with their written descriptions.
