Classifying figures by features is a fundamental geometry skill. Use this lesson plan to teach your students how to categorize triangles by internal angle types.

Students will get hands-on experience manipulating shapes in this preschool-friendly activity. With the help of shape blocks and worksheets, little learners will get the hang of squares, triangles and rectangles in no time.

Use this great lesson to get your students interested in learning about basic shapes! This lesson integrates a sensory activity with learning and lets students get a little messy.

Use a scavenger hunt, art activity, and stickers to help kindergarteners understand shapes and positional language.

In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

Make a math mystery! In this lesson, help your students understand the relationship between addition and subtraction and how a missing addend word problem is represented with a number sentence.

Shapes, shapes everywhere! In this lesson, your students will identify shapes and differentiate between the geometrical figures. They will also learn about sides and angles in every shape.

Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.

Introduce your class to composite shapes with this lesson that reviews geometric shapes and makes use of tangram puzzles. This lesson will give your students a strong base for learning geometry later on in their school careers.

Students will "bee" happy that they got to practice their size differentiation skills with this fun collage activity. In this lesson, students will size sort rectangles from longest to shortest to create a bright beehive.

Identifying shapes and colors will come easily to students after listening to songs, playing bingo, and coloring a worksheet!

This lesson on perimeter will let your students walk around the class to see the border, use a measuring tape to measure the walls in their classroom, and enable them to understand how math is related to real life!

In this lesson, your students will get hands-on practice comparing quantities! Students will compare using buttons, blocks, and their classmates.

Give your students some early practice with shapes using this simple lesson. Young learners will have a great time creating shapes using pieces of string.

Double dominoes! Get your students excited to add with dominoes and playing cards. This lesson is a fun way to help your students continue to learn to add.

Music, hands-on practice, and coloring by number will make this cool addition lesson a favorite! In this lesson, your students will practice adding numbers to five.

Number facts are related, just like families! Help students learn all about fact families while they make fact family trees!
