Your students will become junior math detectives as they hunt down the missing side of a rectangle by applying the area formula for rectangles. The only clues they have are the rectangle's area and the measure of one side.

In this lesson, students will listen to, discuss, and understand two perspectives on a difficult situation. They will flip a coin, with each side representing one side of the story, and role-play the perspectives and reach a resolution.

Students will solve area problems by multiplying side lengths for rectangular shapes in real world contexts.

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.

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.

Good writers begin with a knowledge of who their audience is. They shape their piece knowing that there will be a certain kind of reader on the other side. This lesson will help young writers cultivate an awareness of their audience.
