This short video and interactive assessment activity is designed to teach fourth graders about multiplication of lengths (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about subtracting lengths in meters.

Students design, build and test model race cars made from simple materials (lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape) as a way to explore independent, dependent and control variables. They measure the changes in distance travelled with the addition of mass to the vehicles. Students also practice the steps of the engineering design process by brainstorming, planning, building, testing, and improving their "mint-mobiles."
