Angles, angles everywhere! Help students learn to recognize and count angles with this fun worksheet. By looking closely at the various shapes, students will gain practice classifying and sorting shapes based on how many angles they can identify.

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.

These dogs and cats just can't seem to figure out where to stand! They need some help sorting themselves out.

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.

Students get to practice measuring angles using built-in protractors in this fun geometry activity! After measuring, they'll put their angle knowledge to the test by classifying each angle as acute, obtuse, right, or straight.

Help your students determine if a shape is regular or irregular!

Use this handy worksheet to help your students review those tricky polygons!

Challenge your third grader to identify acute, right, and obtuse angles with this geometry worksheet.

In this 3rd grade geometry worksheet, your child will complete each polygon using a ruler, then identify what type of polygon it is.

This worksheet will introduce your child to the three types of triangles: the equilateral triangle, the isosceles triangle and the scalene triangle.

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.
