Number Bonds complete

EVERY child needs to know the basic number bonds which lie at the heart of all mental arithmetic. This app will challenge you 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 all totals 0-12, then 20, 50,100, 200, 500 and 1000.

There are twenty pages to work on and twelve of them come in pairs.

The first page in each pair provides endless sets of number tiles with which to play at making the required totals, using only drag and drop.

The second page in each pair presents you with 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.

Each page has its own scoreboard where you can keep an eye on your success and progress, measured in terms of both accuracy and speed.

As you progress up the difficulty ladder you can ask for each new set of numbers to be multiples of 50, 10, 5 or 1 (the hardest).

Age range: 5 - 10
