Division World. All the cats are on the board; deal them out fairly until none are left. Share twelve into three rows and see how many each row gets, then turn the same cats about and see twelve in rows of four. It is the multiplication picture with one side already drawn. Fractions World. Cut a cushion into equal pieces and let the cats take some. Make a half, then find that two quarters and three sixths make exactly the same half. Later stages ask for every way to make it. All Worlds. Every world is now one subscription with the first week free. Families who bought a world before keep every world, with nothing to pay. Colouring opens straight from its paintbrush on the home screen.
