Number Bonds to 1000 for iOS

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 10, 20, 50,100, 200, 500 and 1000. 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 50, 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.Age range: 5 - 10PAGES INCLUDEDnumber bonds of 10number bonds of 10: flash cardsnumber bonds of 20number bonds of 20: flash cardsnumber bonds of 50number bonds of 100number bonds of 200number bonds of 500number bonds of 1000
