Here is a chance to practice perimeter, measurement, and develop additional vocabulary. These are fun homework activities for students to do by measuring things in their house with a unit of measure they find at home. Later, they can revisit the activity using inches or centimeters. Since it is tactile, active and a relevant homework activity, even your most reluctant students may choose to do it.
For our ESL students, it is also an activity to build their vocabulary for math and specific items around the house.
