Numberjacks - Series 1 - Sphere Today, Gone Tomorrow

Animated numbers solve real-world mathematical problems with help from children. 3 is playing keepy-uppy with her boing ball and she boings the ball around the room. As 3 and 4 try to avoid it, 5 and 6 come in and order is restored. A girl has got a problem with her marble run - the marbles are not working. Number 6 takes the mission as circular objects have turned into cubes.
