Strengthen your students' understanding of cubic units and volume! They'll solve a realistic problem and explain key ideas about volume. Use this lesson on its own or use it as support for the lesson Volume and a Building.

Students will use the inverse relationship between multiplication and division to complete an area formula in a real-world situation. Use this lesson on its own or as support for the lesson The Case of the Missing Rectangle Side.

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

Students will use their hands to mold clay into shapes, then divide those shapes into equal and unequal quarters.

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.

Students will begin to calculate volume of different rectangular prisms using base ten cubes and then transition to using the formula V = L x W x H. Students will then practice using the legendary fifth grade activity, Cootie Catchers.

Students will love composing shapes using tangrams in this hands-on lesson! Use this plan alone or as a support lesson plan for the Tangrams: An Ancient Chinese Puzzle lesson plan.

Use this lesson to introduce the concepts of capacity and volume with young learners. This hands on lesson can be used as a scaffolded pre-lesson to Capacity Comparison.

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.

Help students visually represent multiplication with mixed numbers and whole numbers. Use this lesson as a standalone lesson, or as support for the lesson Multiplication of Mixed Numbers with Area Models.

Practice calculating perimeter with the placement of carnival-themed games with given rectangular dimensions. Your students will use grid paper to determine the location of all the games they choose to make the perfect carnival.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Planning for a substitute in the classroom has never been easier than with this daily sub plan! Your substitute can keep your students learning in your absence by using these lessons, worksheets, and activities.

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.

Refresh students on the relationship between decimals and fractions when they multiply to find the area! They will find the area of a location in a picture by converting mixed numbers to a decimals and then using the area equation.

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.

Look all around! We can find 2D shapes inside 3D shapes wherever we go! In this lesson, students will sort shapes and recognize the 2D components of common 3D shapes.

This is a fun lesson for your students to learn shapes while playing an engaging matching game. Your students will also get to practice their fine motor skills in this lesson.

It’s magic! In this lesson, students will “magically” move shapes together to form new shapes. Clay and toothpicks equal hands-on fun! Tangram challenges are provided for those students who need that little extra challenge.

With this activity, students will identify shapes, build 3-D shapes, and practice describing shapes with a partner.

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

How do you build spatial reasoning, critical thinking, and problem solving skills while doing something that is fun? With tangrams! In honor of Chinese New Year, this lesson introduces your students to the Chinese puzzle of tangrams.

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.

2D shapes are all around us! In this lesson students will explore the properties of four different shapes—triangles, circles, rectangles, and squares! They will learn that they can find these shapes anywhere in the world around us.

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

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?
