Created by a former engineer and elementary teacher. Every printable is tested with children before release.

My students loved it!
I used these activity cards with my 3rd grade students and they loved them. They had fun building the 2D and 3D shapes with marshmallows and toothpicks. It was also an educational experience as we worked together to determine the number of sides and vertices for each shape. Thank-you!
