Help kindergartners learn to distinguish between two- and three-dimensional shapes with this inviting shapes maze! 

Assess your students’ understanding of the differences between 2-D and 3-D shapes using this shape assessment.

This is a great activity to assess your students’ understanding of geometry and fractions! Students will draw lines to divide various shapes into equal shares and then color in a portion to match the given fractions.

Students explore the relationships between the side lengths and angle measures of triangles in this seventh-grade geometry worksheet!

Can your kid tell the difference between 2-dimensional and 3-dimensional shapes? Kindergarten is a good time to start!

This exercise facilitates meaningful interactions between partners by giving each one different pieces of necessary information to explain the attributes of a shape.

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.

Symmetry is all around us, even in the letters we use in the English language! Use this fun geometry exercise with your students to give them practice identifying and drawing lines of symmetry.

Triangles, trapezoids, rhombi...oh my! Identifying different shapes is an important milestone for young learners. Use this colorful activity to assess your first graders’ abilities to recognize and differentiate between 2-D shapes.

This multi-part worksheet helps students practice identifying the differences between regular and irregular hexagons while also reviewing their knowledge of composite and prime numbers.

Can your students differentiate between a pentagon and a hexagon or circle? Can they explain what makes these shapes unique? This resource will give your students practice identifying the characteristics of a pentagon and comparing it to other 2-D shapes.

Can your first graders tell the difference between a square and a cube? How about a triangle and a cone? Use this geometry assessment to gauge your students’ abilities to use attributes to sort 2-D and 3-D shapes.

Hexagons are hiding in plain sight throughout this worksheet—all you need to do is count the sides of each shape to identify them! This is a great geometry activity to help your students practice identifying and differentiating between 2-D shapes.
