There are 6 ways to sort these cute pups and help young children build key early years skills. This Sort-‘Em-Up Pups set is ideal for sorting activities, colour recognition, number recognition, and fine motor skills activities in the classroom. Sort the pups by height, weight, colour, number, and ear and tail patterns – no two pups are alike! Then group them in their fenced-in playpens or store them in their kennel.
