My 4 year old, 9 year old, and 13 year old are playing darts (magnetic not the dangerous kind) right now. We are asking Christian "what number did you land on?" when he hits the board so that he can work on number recognition.
We don't ask him for every throw, or he would catch on, but every few throws and when he lands on a number that might be familiar with, like 1-9.
Anyway, I thought I would share that in case someone wanted to know a fun way to teach number recognition.
Of course, the older kids could keep a running score in their heads or they could add or multiply their HITS to have a total for each throw - to work on that.
What else? I guess you could pretty much use a dart board much like you use the game MUGGINS!
