Peg + Cat (2013)

Meet Peg, a curious and spunky preschooler, and her feline companion, Cat, who will rely on math “to tackle social and relationship issues and everyday problems like cleaning up a messy bedroom,” Rotenberg says. Some of their dilemmas may be zany — like how to get 100 chickens back into their coop or how to feed a horde of hungry pirates with just one banana — but it’s all solvable via mathematics and a zippy song.
