This app is in regular use in schools throughout the UK, USA, Australia and New Zealand.

Number bonds are an important part of the school curriculum. Here is a fun game to help children learn and practice their number bonds. It is aimed at children aged 4 and over.

There are 2 modes:

1) A simple number bonds to 10 screen for younger children. It requires a single tap of the correct number to answer each question. How many points can you score before losing all 5 lives?

2) A more complex 20-100 number bonds screen which uses a keyboard for entering higher numbers.

You can earn up to 8 smiley face rewards per game. Also try and see how many points you can score using the optional 100 second timer!

The whole game is themed like a lovely classroom blackboard from the 70's.

No ads and no in-app purchases.

A really great way to learn and test number bonds. Both my kids love it. Great developer support as well.

A must for kids, and adults!

My 6 year old thoroughly enjoys playing with this app, he's found it very easy to play and it has helped develop his mental arithmetic skills. An addictive learning game, which I, as a 35 year old, have also found to be enjoyable!!! I can't wait for the follow up!
