More rain today, which means more crazy kids today. One way to keep kids engaged indoors is to challenge them to build a marshmallow tower. Give you kids a stack of toothpicks (don't forget to have a quick safety chat with them about not poking their sister in the arm, ear, eye, etc) and a handful of marshmallows (minis or regular sized) and let them build away. Tell them you want the highest tower they can build, or the longest bridge, or the strongest structure. Challenge them to get build a tower that can hold a stuffed animal or that can withstand an "earthquake" (them stomping on the floor beside the tower). Be creative with what you ask your kids to be creative with!
If you have a couple kids, have them work on team building by collaborating on the challenge. They're having fun while building spatial ability and teamwork.
