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.

Let's divide! In this hands-on lesson, your students will get in on some fraction action when they pair up to create and compare fraction models with the same denominator.

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.

Facilitate rich math conversations with this lesson on finding the missing information in problems related to the area of rectangles and squares. It may be taught by itself or used as support to the lesson Finding Area: Furnishing A Room.

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.

Teach your students to use an area model to solve multiplication problems with a two-digit factor.

Young mathematicians will enjoy demonstrating their skills with this lesson on finding area. It addresses the concepts of length, width, and square units.

In this lesson, your students will think about situations that require them to calculate area. Use it as a standalone lesson or as support to the What Is the Area of Your Classroom? lesson.

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.
