You can use any item small enough the students can grab with their toes. We use the colored sticky notes. Just peal one off, fold it together and throw them around the room. Designate a location on the floor for 2 pads or blocks that the sticky notes will go on top off. When your ready to start, explain to the students they can only use their toes to grab the sticky notes. They must lift the leg up and hop over to one of the 2 designated pads and place the sticky note on top of it. Once all the sticky notes have been picked up and placed on the blocks, the round in over. This a great drill for building balance while teaching the students the valuable lesson of the chamber.
