Representing Multiplication - arrays and number lines Representing Multiplication - arrays and number lines

Represents multiplication using an array and by jumping on a number line. Great for developing an understanding of multiplication by partitioning.

ITP Multiplication Facts ITP Multiplication Facts

View full screen in your browser.  This ITP allows you to represent multiplication as repeated addition using a grid of blocks or counters.It can be used to develop children’s understanding of multiplication and to develop links between the different representations and notation. The dynamic images should help children to understand why 5 x 9 means that the 5 is multiplied by the 9, and to recognise that multiplication is a commutative operation.

ITP Grouping ITP Grouping

View full screen in your browser.  This ITP allows you to display up to 30 counters or shapes on the screen. You then select a number to be the divisor in a division calculation. A number line displays the number to be divided. As individual counters or shapes are clicked and dragged to form a group the size of the divisor, they change colour. Once a group equal to the divisor is selected, it ‘jumps’ to the number line. In this example 22 counters were chosen and the divisor set to 5.
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. Four more counters have been dragged together and the fifth is about to be selected. The answer to the division calculation is shown at the bottom of the screen.
The ITP can be used to model division as grouping and to link this process to jumps on a number line. It can also introduce children to how remainders are recorded in the answer.

ITP Multiplication Array ITP Multiplication Array

October 2012 - I have added a new game which represents multiplication on a number line and using a dotty array. It is ideal as an introduction to the grid method, as it provides a concrete image of how and why we partition numbers to multiply. Click here to play.
