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 learn to convert metric units by applying concepts in word problems. Exercises and worksheets incorporate length (meters), and optional practice offers more instructions on mass (grams) and volume (liters).

Are your students having trouble taming run-on sentences into a more manageable length? In this lesson, your students will learn to not only recognize a run-on sentence, but also how to stop it in its tracks.

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

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.

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.

Finding the area of a rectangle is a key measurement skill to know. In this lesson, your students will enjoy practicing this skill by determining the area of their classroom.

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 your students decorate their own room with this lesson that has them use area to place furniture in a room.

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.
