2nd and 3rd Grade Classifying Two-Dimensional Shapes Resources

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


Classifying Shapes

Review second grade geometry concepts from two- and three-dimensional shapes to symmetry with this helpful shape study guide.

Shape Review: Line Segments, Symmetry, and More

Craft a paper rocket in this hands-on activity inspired by the life of Mae Jemison!

Rocket Like Mae Jemison

Work with 2-D shapes and famliiarize yourself with concepts like halves, thirds, and fourths in this hands-on geometry workbook. Children practice identying parts of a whole and develop a meaningful understanding of fractions through exercises, games, and

Learning About Equal and Unequal Shares

Build a solid geometry foundation with these hands-on shapes. Kids can practice identifying attributes of 2-D and 3-D shapes, then put their knowledge to the test by drawing and making 3-D shapes.

2-D and 3-D Shapes

Geometry isn't so scary when it comes with colorful designs and easy-to-interpret illustrations! In order to take on algebra later on, your student will first need to conquer basic geometry.

Geometry Shape Up

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.

2-D Shapes: Fill in the Table

Build reasoning and logic skills with a fun geometric shapes puzzle!

Color a Tangram Template

Get ready to identify and circle the correct fraction! After finishing this worksheet, your second graders will have a better understanding of equal parts.

Identifying Halves, Thirds, and Fourths 

Help your third-grader learn to recognize quadrilaterals with this geometry worksheet.

Naming Quadrilaterals

Geometry in third grade introduces kids to the idea that shapes have different categories (rectangles, rhombuses, etc..) attributes (four-sided, etc...) and areas of different values. This lesson, designed by our curriculum experts, provides the guided instruction and practice that third graders need to conceptualize shapes in a deeper way. For more practice, download and print the third grade geometry worksheets recommended as part of this lesson.

Geometry 5

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.

Comparing 2-D Shapes

Use this worksheet as a formative assessment for your students as they study the characteristics of polygons.

Categorizing Shapes Check 

Kids get to know shapes better by counting their line segments, endpoints, and angles, and record the info in this handy chart.

Shape Basics: Lines, Endpoints, and Angles

4 lines make a quadrilateral! Help your child make various shapes with the dots in this worksheet.

Making Quadrilaterals

This fun geometry activity challenges your students to identify, color, and count all the trapezoids and other quadrilaterals hidden amongst a variety of two-dimensional shapes.

Trapezoids and Quadrilaterals

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 

Kids build their shape knowledge by identifying congruent shapes.

Shape Basics: Congruent Shapes

Symmetry is all around us, even in the letters we use in the English language! Use this fun geometry exercise with your students to give them practice identifying and drawing lines of symmetry.

Alphabet Symmetry

Here's a fun way to practice shape identification! Use your knowledge of plane figures to color in this picture.

Plane Figures

Trapezoids are quadrilaterals with only one pair of parallel sides. This worksheet will help your students learn to identify and distinguish trapezoids from other two-dimensional shapes with the help of a word bank.

Identify Trapezoids

On this geometry worksheet, your third-grader will look at the different triangles and label them as equilateral, isosceles, or scalene

Identifying Triangles

In this geometry exercise, children calculate the perimeter of various trapezoids by adding up the lengths of their sides.

Trapezoid Perimeters

Can you see the symmetry? Use this resource with your students to practice identifying shapes with symmetry. After your students identify the symmetrical shapes, they will draw a line of symmetry.

Shapes with Symmetry

Use this fun math resource with your students to integrate geometry and fractions. Your students will use hexagons to enhance their understanding of fractions by creating their own visuals.

Hexagon Fractions

Help your child learn to recognize scalene triangles with this worksheet.

Scalene Triangles

Use this glossary with the EL Support Lesson: Naming Shapes and their Attributes.

Glossary: Naming Shapes and their Attributes

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.

Trapezoids and Parallel Lines

Help your third-grader learn to recognize the identifying features of a polygon on this geometry worksheet.
