Many animals, like people, enjoy spending time with their friends and family. Many groups of animals have their own unique names. Did you know a group of gorillas is a called a band? And a bunch of billy goats is a tribe? Following in the footsteps of Multiply on the Fly (multiplication), What s New at the Zoo? (addition) and What s the Difference? (subtraction), this rhythmic, fun-to-read-aloud book introduces children to division as they conquer bands, tribes, mobs and more."
