Practise your numeracy skills with the animated number-crunching heroes as they solve some mathematical problems.


The Numberjacks are superheroes - animated numbers who solve mathematical problems in the real world with input from real children. The series is aimed at 4-5 year olds and will help them develop early maths skills, knowledge and understanding.

The Numberjacks' base is inside a sofa. Each episode focuses on one mathematical concept or idea to encourage learning with numbers.

In each episode, the Numberjacks get a call from an agent (a child) telling them about a problem. After comedy and thrills, the problem is solved and the Numberjacks return to base. The episode ends with a question for the children watching at home. This will encourage children to look for, and discover, shapes and numbers around the home.

The educational value of the show

Numberjacks helps children to:

  • Develop early numeracy skills, such as number recognition.
  • Search and find shapes and numbers around the home.

The younger Numberjacks - 0, 1 and 2

The problems are sometimes caused by the younger Numberjacks escaping from the sofa and inadvertently making things go wrong. More often though, the source of trouble is one of the five Baddies.
