App Store Description

EVERY child needs to know the basic number bonds which lie at the heart of all mental arithmetic. This app gives you a challenge in a fun way. It allows you, in a graded set of pages, to increase the level of difficulty to suit your own progress. There are pages to pair up numbers that add to make 10, 20, 50, and 100.

Each page provides (1) endless sets of numbers to practise with, using only drag and drop, and (2) a scoreboard to help you keep track of your progress. The scoreboard not only records the accuracy of your answers but your speed as well.

As you progress up the difficulty ladder you can ask for each new set of numbers to be multiples of 10, 5 or 1 (the hardest).

For totals of 10 and 20, a further page presents you with number bonds questions on flash cards. You can use these pages either in ‘play’ mode or in ‘test’ mode. Playing with the flash cards helps you to get used to how the page works, and testing yourself gives a target to aim for: i.e. answer all the questions posed in the shortest possible time with as few mistakes as possible.

If you master the mental arithmetic required on these pages, then you are ready for the much bigger challenge in the ultimate app of this group!
