S has finally fallen in love with games and I love to play them with him. "Go Fish" is a favorite. We have this version and I like it because it reinforces upper and lower case match-ups for him and it also teaches the names of baby animals, but it got me thinking that there's nothing special about this deck that makes it "Go Fish". You could also use any deck of flashcards that has pairs in it (colors, shapes, letters, numbers, etc.) or you could buy two of the same deck of flashcards to create an educational "Go Fish" game. Dollar Tree usually has a selection of simple flashcards.
