Teach or review the concepts of perimeter and area while getting your students up and out of their seats. This activity is editable so you can change the items to measure to suit your classroom. I have used this activity to measure to the nearest whole number, 1/2 inch, 1/4 inch and 1/10 inch. It is a good way to differentiate for your students. I also like to have several types of measuring tools (small see through plastic ruler, standard one foot ruler and yardstick) to see which one the students will pick. Enjoy!
