This set of 72 cards can be used independently or with the Once upon a Seashore curriculum (see Related Products, below). In five clues or less, children provide the answers to questions on these cards. The cards teach about whales, seals, sea lions, birds, fish, crabs, sea stars, urchins, anemones, snails, seaweed, jellies and plankton. Twelve games cover such topics as predator-prey relationships, niche, and classification. For ages 6 to adult.
