Numberblocks
Cuboid Castle
The Numberblocks build a play fort for the Numberblobs, using a series of cubes and cuboids and learning about solid 3D shapes. They complete a magnificent play fort, only to realise they have forgotten about the ‘pyramids and prisms expansion pack’. With Three reading out the instructions, they learn to build a see-saw and complete the play fort, only to find that the Numberblobs have more fun playing with an empty cardboard box.
