Get your kindergartener in shape for math! Here's a great introduction to comparing sizes: small, medium and large.

Use this resource to review 2-D shapes with your young mathematicians. Students will identify the names, number of edges, and number of vertices of common shapes as they work to fill in the blanks of this 2-D shape chart.

Shapes are everywhere! Use this fun real-world inspired worksheet to practice identifying and comparing 2D shapes found in everyday activities.

Angles come in all kinds of shapes and sizes—can you spot them all? Use this resource with your students to practice finding all the angles in 2-D shapes. Your students will then be challenged to identify right angles in two-dimensional shapes.

Use this resource to help your students develop their understanding of trapezoids and other two-dimensional shapes. Students will compare the attributes of trapezoids to those of other plane figures, such as triangles and ovals, in this geometry activity.

What makes a hexagon a hexagon? How is it different from other polygons? This handy geometry resource with help your students to practice identifying the characteristics of a hexagon and comparing them to other two-dimensional shapes.

What makes a sphere unique compared to other shapes? Does it share any similarities? Use this resource with your young mathematicians to practice identifying the characteristics of this three-dimensional shape and comparing it to other shapes.

What makes a trapezoid unique? How is it different from a hexagon or a pentagon? Use this resource with your students to practice identifying the characteristics of a trapezoid and comparing them to other 2-D shapes.

A key characteristic of trapezoids is that they have a set of parallel lines—lines that never intersect. Use this helpful geometry resource with your students to practice identifying parallel lines in trapezoids and comparing different 2-D shapes.

What makes a cylinder a cylinder? How does it compare to a cube or cone? Use this great geometry resource with your students to practice identifying the characteristics of a cylinder and comparing them to other three-dimensional shapes.

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.

What makes a cone different from a cylinder or a cube? Use this helpful resource with your students to take their geometry skills to the next level as they practice identifying the characteristics of a cone and comparing them to other 3-D shapes.

Give your students a chance to sort polygons into categories that make sense to them.

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

This worksheet challenges your preschooler to decide which two triangles are the same shape and size.

Fourth grade mathematicians will need to use their geometry skills to figure out the length of the pictured rectangles' perimeters, then make their own.
