Numberjacks - Series 1 - Into the Teens

Animated numbers solve real world mathematical with help from children. Numbers 3 and 4 are in the gym playing hide and seek, but 3 counts too fast before 4 has found anywhere to hide. Number 4 shows 3 how to count slowly but 3 gets bored and pretends to collapse. They are interrupted by the Agents calling in - a boy on the beach had a sandcastle when suddenly five more appear, then another five more.
