Sum Builder Challenge

Can you crack the Sum Builder Challenge?

This puzzle tests your speed maths and challenges you to complete the mountain of numbers as quickly as you can.

To do so you need to perform addition and subtraction sums, and so they are also great at learning to re-arrange simple equations, a very important maths skill.

We suggest that you do one sum builder challenge each day and time how long it takes you to complete. Then over the course of a few weeks you should start to see your times come down as you get more comfortable at solving them and doing the maths and calculation sums in your head!
