Duration: 15 minutes
In the Cosy Room, 1, 3 and 4 play Stepping Stones with triangles and rectangles to get from one side of the room to the other. A girl's blackboard is changing size, as is a man's writing paper and the flag on the back of a bike. In a school, kids are playing with hoops that change size.
6 flies out and discovers out the problem is down to the Shape Japer. The Numberjacks realise they are dealing with rectangles, triangles and circles. They sort the shapes, even when they become extreme shapes, and discover that the stretched circle is called an oval.
