This is a new version and is also available as an ipad app. You can play the old version here.
Drag the flag to the correct position on a number line. Lots of choice over level, including whole numbers, negative number and decimals. Can be used to teach place value, approximation skills, and reading varying scales.
Choose one type of number line or for more of a challenge you can select several. Work quickly to get more time, build your score and climb up the leaderboard.
Estimate the number the arrow is pointing to, then calculate the correct answer when you are told your error. A great game to help develop an understanding of place value, reading scales and to practise mental addition and subtraction. There are lots of levels to play; inc. 0 to 10, 0 to 100, 0 to 1000, and levels involving negative numbers and decimals.
