It's a short, quick counting game and we played over and over again! Below are a few more photos and a link to the game if you want to download it for yourself.
Math Grid Game: By the way, you can also use the ocean animal sheet to play a simple math grid game. Keep the animal sheet intact and print out one sheet for each player. Have each player take turns rolling the die and covering up that number of animals. The first person to cover all the animals wins that game.
You can also use these cards with your kids to sort into vertebrate and invertebrate groups.
