Stand or sit in front of your partner and start to draw numbers or letters using one finger. The partner has to read it once you are done and so you verify your communication. Change places and after a while progress to drawing two different things using both hands and reading them in turn. Going through the numbers between 10-40 is a good place to start.
Repeat this drill using the feet and your body by walking and you will gain a lot of awareness and coordination while having fun.
