4.G.A Worksheets, Workbooks, Lesson Plans, and Games

Help students learn how to use a protractor.

How well do you know your angles? Let's find out! Use this geometry resource to help your students identify and differentiate between important angles such as acute, obtuse, straight, and right angles.

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.

Assess kids' understanding of geometry with this sheet.

Assess your students’ knowledge of geometry concepts from polygons to coordinate planes!

In this second grade geometry worksheet, your child will practice finding the line or lines of symmetry on a variety of different shapes.

Geometry is everywhere! Lines, line segments, and points are all around. In this lesson, your students will learn about important aspects of geometry.

Get your students up and moving as they learn the basics of geometry. Your competitive students will love this game and put their new skills to the test with a worksheet.

Symmetry is everywhere, but it's often hard to notice. This lesson explores a few ways to identify it. By folding and making mirror images for different shapes, students will discover a new world of symmetrical figures.

In this lesson, students engage in interesting hands-on activities that help them discover the properties of parallel, perpendicular, and intersecting lines. Your little mathematicians will have a blast as they learn about geometry.

In this lesson, students will use a multi-sensory approach by engaging in a hands on activity with toothpicks to create, explore, and learn about the properties of four different types of angles.

Teach your students about symmetry with real life objects! Have them draw lines of symmetry for various shapes, food items, and objects.
