In, On, Out

A great game for prepositions is give the kids a paper cup and a marble each. They put it on the cup and say on, then using one hand, flip the cup over and get the marble "in", then drop it "out" into the other hand. They love trying to get the hang of it and is a great excuse to teach "I did it!". They will also think you are amazing cause you can do it first time.
