In this lesson, your students will measure the lengths of items and then make a line plot to show the measurement data. They will get hands-on by measuring and surveying the class.

Help your students use rulers in the classroom with this lesson! Encourage them to measure items around them using centimeters to understand shapes and sizes.

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).

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.
