This worksheet corresponds with my PowerPoint over mollusks. The formatting is with fill-in-the-blanks. Students can guess the word from the PowerPoint and then fill it into the blank. The three major groups of mollusks are described: Bivalves, Gastropods, and Cephalopods. Animals mentioned are clams, mussels, scallops, oysters, snails, slugs, octopus, and squid.
