Get your students explaining estimations and measurements of liquid volumes and masses of objects! Use this lesson independently or alongside *Estimating Measurements of Mass and Volume Using Metric Units.*
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.
In this hands-on lesson, your students will get to sharpen their measuring skills as they measure lengths of items in your classroom to the nearest quarter inch. They'll get to then use their data to create line plots.
