Students will learn out how to partition a rectangle using by partitioning shapes with rows and columns.

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.

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.

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

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 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!

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.

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.

Teach your students four simple steps to help them solve multiplication and division word problems with confidence.

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.

Slice those pieces and mix it up! In this lesson that follows “Slice It Up! Part One,” students will begin recognizing different ways to create equal shares in whole shapes, creating a fraction poster by the end of the lesson.

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

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.

Fill ‘em up! This lesson teaches students to compare how much different containers can hold. Get ready for some overflowing fun!

Use this lesson to teach your students how to determine if they should use addition, subtraction, or both operations to solve a word problem by following four simple steps.

It’s pizza time! Students will be introduced to the concept of partitioning shapes to create fractions that demonstrate halves, fourths, and eighths. This lesson is the first of two lessons that address second grade fraction concepts.

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!

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.

Mae Jemison was the first African American female astronaut to enter space. Use the Get to Know Mae Jemison lesson plan to learn more about this famous scientist. Children will then read and write about her, and create their own paper rocket.

This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.
