Numberblocks Numberblocks follows the adventures of block characters in Numberland, with the number of blocks determining which numeral they stand for and a tiny black floating number above them to show how many blocks they are made of, which they call a Numberling. When one of the blocks hops on top of another, they transform into a different character to make a new number. The show helps toddlers and young kids learn numeracy skills, especially how to count and do simple maths.
