This app is a great tool for children to practice their idea of different scales in mathematics: is 8 bigger than 18? Or vice versa? And what about 180? What seems to be obvious for adults is something all children first have to learn. This app helps children to build a mental image of a number line which is essential for calculating. **** Game modes **** Mode 1: Find the correct position Drag the owl to the correct position on the number line branch to a given number. Are you close enough to feed the owl? Take care of falling nuts! Mode 2: Find the correct number The owl moves to a particular point on the number line. Enter the number you think corresponds best to her position. (iPad only) The better the child is, the higher it will rank on the high score table! **** Settings **** - Adjustable difficulty - Number range: 10, 20, 100, 1000, 100'000

"Lazuli Times Tables" is a brand-new app from the multi-award-winning “Lazuli” learning system. It’s designed for children starting in second grade, as soon as they begin learning the multiplication tables. In 15 engaging and varied games, kids practice multiplication through a range of motivating challenges. To reinforce learning over the long term, there are also 14 exercises to master all related division tasks. As a special challenge, some tasks must be solved against the clock—while funny characters provide playful distractions. This very skill—staying focused despite disruptions—is exactly what children need at school and in everyday life. Each exercise can be selected individually and repeated as often as you like, helping develop cognitive skills in the best possible way.
