Earth Day Math Games Online 2016:
Show a tutorial for how to make a solar oven a few days before Earth Day. Here is one that could be made from a pizza box!
Tell the students to bring their own supplies from home (cardboard boxes, plastic wrap, aluminum foil, tape) and give them time to make them when they first get to school. It took our class about 2 hours. The math involved is awesome, measurement, measurement and more measurement! I brought the graham crackers, chocolate, and marshmallows and they melted like crazy in the sun. It was super fun! Here are a few photos.
