Take your class for an imaginary stroll along the beach and discover the magical world of shells. Start this unit with a chart for students to fill in as they learn about Shells. Give the students a chance to predict some facts about shells. Use the "Observing Shells" task cards. Which shells belong to the same group? Let the students classify the shells, feel their textures and try to identify some shells. A detailed teacher guide includes suggestions for the teacher and tips of how to set up the activities. Included in this unit are informational cards on mollusks and shells; reading cards and task cards; and activities that focus on observation, research, word study, and art.
