Birds of North America 100 Piece Memory Card Game
I really loved playing this game with my 4yo, and can tell he's quick to being independent with it. Using all 100 cards is a bit intensive, and if you want to reduce the size of your memory game, you have to go through and match the ones you want to remove, but I like that it will grow with him and remain a challenge as he begins to read. I like the passive learning that takes place of all the species, and love that it includes the latin names for the birds as well. I named every bird as we turned each card over, and he said, "You really know your birds!" :)
