Let your fourth grader play triangle detective: can she spot the acute triangles on this worksheet?

Pentagons are easy to spot—if you know what to look for! Help your students develop an understanding of this five-sided polygon and practice 2-D shape identification with this great geometry resource!

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.
