A phylum (subcategory) of invertebrate. The set includes an overview of echinoderm characteristics and 3-part photo cards for 6 echinoderms (feather star, pencil sea urchin, sand dollar, sea cucumber, starfish, sunflower sea star).

Then, mix with other categories for sorting, comparing, and contrasting. Later, extend classification work by exploring the key features of echinoderms with Parts of the Starfish 3-Part Photo Cards (SC582, SC580).More information below
