rings (or play bracelets, like I used)
The pictures are pretty self explanatory. But just in case, put the playdo on the bottom of the bowl, stick the spoon in the playdo, then toss the rings to try and make it on the stick.
This was not Riley's favorite, I don't think she had the motor skills to throw the rings that well. Next time, I might just have her throw them into a bowl, with out a stick. I'm sure that kids 3 1/2 and older could do it, though.
