【實用教育app】Number Bonds to 1000|最夯免費app-綠色工廠好玩App

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).Age range: 5 - 10
