Teach your students to sort triangles as acute, right, or obtuse based on their internal angle type.

Children will take note of the everyday shapes that surround them in this fun geometry activity.

Build student understanding of the defining attributes of triangles with this sorting activity. Students will cut out different shape cards and sort them into examples and non-examples of triangles.

Fifth graders review types of angles, triangles, and polygons in this handy geometry review.

Children find the unknown angles for five triangles, then identify whether the triangle is right, acute, or obtuse, in this geometry worksheet.

Is your child in need of a geometry review? This worksheet covers the basic 2-D shapes, from circles and triangles to pentagons and hexagons.

Strengthen your child's geometry skills with this printable worksheet. Use this resource with your students to classify two-dimensional shapes like parallelograms, quadrilaterals, squares, and triangles.

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.

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.

Space out with this shapes worksheet, where kids identify basic 2D shapes.

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

Assess your students’ knowledge of geometry concepts from polygons to coordinate planes!
