23/11/17 - new version added. This version is tablet friendly and can be played directly on any device.
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.
I am remaking the ITPs so that they will work on all modern browsers and tablets. They will remain freely available to all without the need for a subscription.
This ITP displays on-screen place value cards to construct and partition three-digit whole numbers. Once the cards are created they can be deleted clicking on the cross in the top left hand corner. By clicking on the number, a card can be dragged around the screen and repositioned. You can have one or two sets of cards on the screen at a time. The value of each place value card is determined using the respective button at the bottom of the screen. Each number on a card can be represented by groups of counters, clicking on the pointer on the card to reveal and hide the counters. The ITP can be used to demonstrate the construction and partitioning of numbers to secure children’s understanding of place value. Displaying two sets of cards you can compare their values and pose questions about their sum and difference. Partitioning the numbers and rearranging them can be use to help children understand how pencil and paper methods of calculation are recorded.
Estimating Numbers on a Number Line - Tablet Version
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.
