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.

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.

Geometry is a core of mathematics in the early years. Help students recognize and draw shapes given specific attributes such as the number of corners and sides. This lesson can be a stand-alone activity of paired with 2-D Shapes!

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.

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

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?

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.
