If they want to get anywhere, students must cooperatively lift the rope handles to move these durable wood walkers. Wide 5-1/2" x 1" thick (24 cm x 3 cm) platforms help prevent tipping and have no foot straps to bind the feet. Features artwork printed on each set so students know where to stand. Foam-padded platform bottoms protect your floors. A combination of lengths will keep the whole class moving. For indoor use only.
