"Numberblocks" follows the adventures of one hundred anthropomorphic block characters in Numberland, with the number of blocks determining which numeral they stand for and a tiny black floating numerical figure above them to show how many blocks they are made of, called a numberling. When one of the blocks jumps on top of another, they transform into a different character to make a new number. The show tries to help preschool children learn numeracy skills, especially how to count and add up.
