Students will work hard to build shapes with straws in this hands-on lesson about the defining attributes of triangles. Use alone or with Know Your Shapes.

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.

This hands-on lesson will get students thinking and talking about how the numbers in fact families are related. Use alone or with the lesson plan Fact Family Trees.

You'll see angles from every angle! Students will describe and compare different angles they see in everyday situations. Use this lesson on its own or use it as support to the lesson Classifying Triangles by Internal Angles.

Students will love composing and decomposing two-dimensional shapes using tangram puzzle pieces. Use this plan alone or to frontload key vocabulary and concepts taught in the lesson plan Know Your Shapes.

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!

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!

Students will explore geometric shapes by creating a painting of a trapezoid.

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.

This lesson helps students understand the difference between polygons. It focuses on the root words of these terms to help students make connections to their prior knowledge, making it especially beneficial for ESLs.

Math meets art in this fun lesson where students create a house for a fact family. Use the scaffolded EL lesson plan alone or with Dots & Dots of Fact Families.

Your students will solve and create shape riddles while practicing their knowledge of shape attributes.

Your students will have a blast thinking about polygons and making these paintings inspired by Wassily Kandinsky!

Geometry meets data in this fun lesson! Students will build a design using pattern blocks and then graph the number of each shape used. This scaffolded EL lesson can be used alone or alongside Graphing Colored Counters.

A hands-on approach makes geometry fun! Use this lesson to teach your students about the basics of perimeter with geoboards.

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.

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

On some level, all humans want to feel peace and to feel loved. In this lesson, students will practice sending peaceful thoughts to themselves and others and discuss how these practices can support peace in their lives and community.

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.

Students will have fun engaging in activities that develop their ability to write sequential step-by-step directions. This lesson helps young learners with being detailed and using transition words in their writing.

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.

In this lesson, your students will break down composite figures to identify 2-D shapes that make them. Students will put together 2-D shapes to create a composite shape.

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.

In this lesson, your students will use their auditory, visual, and kinetic skills to learn about angles. Students will use their artistic and linguistic abilities to learn about angles and lines.

Practice subtraction with art! Help early learners grasp the concept of "taking away" using drawings. This lesson helps students work toward subtraction with numerals, and the mastery of simple shapes.

What's in the bag? This fun math lesson involves using defining attributes as clues to draw conclusions. Young learners will have a great time making guesses about different objects and creating their own shape riddles.

This lesson integrates phonemic awareness and phonics. Using a number of exciting activities, your students will learn about two consonants that come together to make a digraph.

Finding the perimeter of a polygon is a simple process with addition! Use this lesson to teach your students how to find the perimeter of polygons.

Beyond just prefix identification, this meaty lesson taps into your students’ thinking. Using a combination of analogies, constructing, and deconstructing words with prefixes, students will learn the meaning and mechanics of prefixes.

Show your students how coordinate planes can be useful in seeing the distance between various locations! Have them draw shapes on a coordinate plane and determine the location of corners.
