Teaches state names, capital cities and state nicknames for all 50 states. Both my children have used this toy (the older one passing it on to the younger one) and it really helps them in school when they begin to study the states! It's fun too, trying to fit the pieces in (which teaches locations of the states themselves on a US Map!) We are passing it on to my Godson who is 6, and then he will pass it on to his younger brother. It's lasted YEARS to say the very least... Just be sure to keep track of the little pieces, LOL, I've done my share of having to go through the vacume cleaner dust to retrieve a sucked up state!!! RECOMMENDED for age 5+ because of the little pieces.
