Showing Results for sorting and classifying

For students who learn by doing, this exercise will make learning different shapes’ classifications much easier.


Classifying Shapes

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

Sorting Triangles

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.

Sorting Shapes

On the road again! Kids identify 2D and 3D shapes in this sorting game.

2D and 3D Shape Sort: Car

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.

Triangle Sort

Sorting takes on a new challenge for students in this activity which engages their critical thinking skills. As students determine defining attributes, they’ll figure out what makes a shape a shape!

Shape Sort

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

What Kind of Polygon?

What is the name of this shape? Is it a parallelogram or square? Teach your students to classify two-dimensional shapes using a Venn diagram.

Categorize These Shapes 2

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

Polygon Practice

Help your students identify the differences between regular and irregular polygons!

What Type of Polygon?

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.

Categorize These Shapes!

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

Geometry Review: Angles and Polygons

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

What's Your Angle?

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

Three Types of Triangles 

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

Polygons: Name that 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.

Looking at Shapes: Open or Closed?

Get in shape for geometry! From 2D to 3D, polygons to prisms, your child will soon be a shape master. After a review of important terms and concepts, he will practice identifying real world shapes.

Shapes From Every Angle

Students will use their hands to mold clay into shapes, then divide those shapes into equal and unequal quarters.
