The Length in Centimeters Game is an interactive game that allows students to measure objects using an virtual centimeter ruler. A positive response is given when the measurement is correct; an negative response is given when the measurement is incorrect. When incorrect the students have the opportunity to remeasure. The resource could be improved by adding more objects to measure. With only 5 items to measure, students would complete the activity in a short amount of time. In addition, use of this activity in the classroom would require internet access.
