Equilateral Triangles

Is your fourth grader reluctant to practice geometry? This colorful worksheet, which explores obtuse triangles, may be just what he needs!

Obtuse Triangles: Identifying Triangles

How much does your fourth grader know about triangles? Can he figure out the missing angle in each of these triangles?

The Missing Angle: Triangles

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

Identifying Triangles

See if your child can find all the triangles hidden on this geometry worksheet.

Count the Triangles

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 

Help your child learn how to identify an isosceles triangle with this geometry worksheet.

Isosceles Triangles

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

Everyday Triangles

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.

Grab your fishing rod and see how well you know the properties of quadrilaterals!

Dino Fishing: Identifying Quadrilaterals

Fourth graders will discover the building blocks of geometry in this unit: points, lines, line segments and rays. Students will explore the properties of different shapes, including symmetry, parallel and perpendicular lines, and 900 angles. Students will apply their understanding as they learn to sort shapes based on these properties.

Geometry 6

Review common plane figures such as rectangles, triangles, circles and squares with your child as you hunt for all the shapes you can find in the picture.

Shape Dimensions

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

In this fourth grade geometry worksheet, your child will learn how to calculate the area of a pentagon by breaking it down into rectangles and triangles first.

Calculating the Area of a Pentagon

Your students will love getting a chance to use their creativity as they review the properties of regular and irregular pentagons while creating their own unique piece of art.

Drawing Pentagons

This workbook will challenge your fourth grader with math formulas, shapes practice and angle activities. Kids will also learn how to find areas and perimeters, classify triangles and calculate time.

Geometry and Measurement

In this fourth grade geometry worksheet, your child will learn how to calculate the area of a hexagon by breaking it down into rectangles and triangles first.
