Numberjacks - Series 2 - On the Move

Animated numbers solve real world mathematical problems, with help from real children. Numbers 3 and 4 are in the gym and play at sliding blocks into the circle. 3 thinks they need recounting if they move. Out on location, a girl thinks the same about her toys, and the waitress, a man and a teacher have the same problem. It's the Problem Blob at work, as 5 discovers. The Numberjacks protect everything from the blobs to stop them moving, but things move anyway, so they are all counted all over again. The Numberjacks send Brain Gain to stop people counting things when they move. All is sorted, and the Blob goes off in a huff.
