Help your third-grader learn to recognize quadrilaterals with this geometry worksheet.

This fun geometry activity challenges your students to identify, color, and count all the trapezoids and other quadrilaterals hidden amongst a variety of two-dimensional shapes.

4 lines make a quadrilateral! Help your child make various shapes with the dots in this worksheet.

Trapezoids are quadrilaterals with only one pair of parallel sides. This worksheet will help your students learn to identify and distinguish trapezoids from other two-dimensional shapes with the help of a word bank.

Kids sometimes don't distinguish between a shape that's open and one that's closed. Here, kids can see the difference as they classify shapes as open or closed.
