Large color photographs show real-world examples of pyramids (Hindu temple, toy tepee) and cylinders (canned goods, birthday candles). Short descriptions flank each photo: "Pantry shelves hold cylinders full of food." Each geometric shape is defined and 2-D and 3-D figures are briefly compared. Appended facts are rather random, but a hands-on activity will appeal to kids. Reading list. Glos., ind.
