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.

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.

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.

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.

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.

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 explore geometric shapes by creating a painting of a trapezoid.

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.

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

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.

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 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.

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.

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.
