Here's an interesting paper project for young mathematicians: creating a 3-D paper cone.

Look closely and you will find… rectangular prisms! Help students recognize this 3-D shape while examining a kitchen scene.

Take a closer look at 3-D shapes with this fun worksheet that challenges kids to find 2-D shapes within 3-D shapes.

Learn more about geometry by creating a 3-D triangular pyramid! Color, cut, fold and glue together the flaps to create a triangular pyramid.
