Practicing subtraction using a thermometer for a number line makes math fun! In this lesson, your students will get more comfortable with subtracting two digit numbers.

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.

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.

Students will love working together to create a display that demonstrates understanding of relative length. Use alone or with the lesson Order Up Measurement.

Help your students learn the standard measures of length and foster critical thinking with this engaging lesson. Use alongside The Smaller They Come or as a stand-alone activity.
