The Whitefish PTA really knocked our socks off by granting my request to buy a box full of Keva planks. These seemingly simplistic blocks require no instructions and are fun for every age. Some students build towers taller than themselves, while others work on mazes for ping pong balls. One small group of girls built a one-story house with rooms.
Making a structure for a ping pong ball proved loads of fun. Students could kickstart the ball, but the structure had to sustain the motion until the end. Video1 Video2
