How Heavy

Break out the balances for this primary grade lesson on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A graphic organizer is provided for recording results, with children drawing a picture of the object and writing down the weight they measured. To ensure the success of all learners, be sure to model the correct procedure for using balances at the beginning of the lesson. This activity would make a great addition to math rotations during a unit on measurement.
