The grid size can be changed to accommodate different calculations. This ITP allows you to set up a multiplication grid to demonstrate the grid method of multiplication for whole and decimal numbers. They will remain freely available to all without the need for a subscription. I am remaking the ITPs so that they will work on all modern browsers and tablets. It can also introduce children to how remainders are recorded in the answer.įor more multiplication and division resources click here. The ITP can be used to model division as grouping and to link this process to jumps on a number line. The answer to the division calculation is shown at the bottom of the screen. Four more counters have been dragged together and the fifth is about to be selected. In the example shown below, 3 sets of 5 shapes have been selected and moved to the number line, which shows each group as a jump. In this example 22 counters were chosen and the divisor set to 5. Once a group equal to the divisor is selected, it ‘jumps’ to the number line. As individual counters or shapes are clicked and dragged to form a group the size of the divisor, they change colour. A number line displays the number to be divided. You then select a number to be the divisor in a division calculation. This ITP allows you to display up to 30 counters or shapes on the screen. This ITP has been remade so that it will work in modern browsers.

The Calculations app is available on Google Play and the App Store.

This game is now part of the 'Calculations' collection, which includes the following 17 games and resources: Column Addition, Expanded Addition, Expanded Addition - Place Value Counters, Number Bonds(2), Addition - Digit Drag, Missing Symbols, Column Subtraction, Column Subtraction using Place Value Counters, Counting on to find difference on a beadstring, Multiplication Grid Method, Multiplication Written Method, Ratio and Scaling Numbers, Representing Multiplication, Division by Chunking Up, Division by Chunking Down, Formal Written Division - Round Up or Down?, Short Division Writen Formal Method.Ĭlick on 'Multiplication' and then 'Ratio and Scaling Numbers'.

Children should see that sometimes it is easier to scale numbers in one 'direction' than the other, and that they can choose the most efficient method.įor more resources involving word problems click here. Designed to help children to visualise the relationships between numbers when answering word problems involving ratio and scaling quantities.
