This game is played the same as traditional Go Fish, except the children are asking for letters instead of numbers. I pass out five cards to each student, and tell them to hold the cards where the picture of the fish is (I have found that preschoolers have a hard time holding cards in their hands, so having this visual cue of where to hold the cards really helps). I then model how to ask for a card (i.e. "Do you have the letter...") At the end, the student with the most matches wins. It takes my students a little help to understand how to play this game, but once they get it, they love it.
I have included capital and lower-case letters on individual cards so you can practice both. There are also blank go fish cards so you can make your own.
I print the cards, cut them, glue onto construction paper, and laminate. I do it this way so that I can glue the picture of the ocean on the back of the card to make them look more official. I have a lot of parent volunteers at my school though that like to work on projects. If you don't have time to glue the back onto the go fish cards, you can still play without it. Honestly I really don't think the students even notice. It's just cuter with the back picture. =)
