Learning to get good at sums isn't normally fun, is it? But here at Childrens Puzzles, we've made a fun interactive and colourful sums trainer, so now you can get your mental arithmetic really good!

All you need to do is enter below how many sums you want to practice, then click the 'go!' button. The player will then give you a range of addition, subtraction and multiplication sums. None of the numbers are bigger than 12, so all will be familiar from your standard times tables. We even record how long it takes you to do the sums, so you can see how you improve over time.

When you have answered a sum, click on check to see if you are right. If so, then click on next for the next question. If you get really stuck on a sum, then just click on next straight away. We hope you enjoy the free maths sum practice tool here on Children's Puzzles! If you have ideas for any other games like this you'd like to see, we'd love to hear your ideas!
