Bubble Pop - Number Bonds
A great way to practise number bonds and mental addition. Levels include: number bonds to 10, 20, 50 and 100 as well as addition pairs with a total of up to 20, 50 or 100. Look at the target at the top of the screen and then aim your bubble to make that target.

As a teacher I know how important it is that children know their number bonds (pairs of numbers that add up to 10, 20, 50 or 100), and can add quickly mentally. Repetition is essential in learning number bonds. This game is designed to make the process fun.

Children have to aim their bubble to make a given sum. As they progress the levels get harder; they have less time, or less bubbles to shoot. Each correct answer is accompanied by an image to reinforce the number bond they have found.

This game will work directly in the browser of any device.

ITP Number Facts
This ITP has been remade so that it will work in modern browsers. It will remain free to use.

This ITP displays up to 20 coloured counters and the corresponding addition sentence. The number of counters you select, appear on the screen in purple. Click on any counter to change its colour, the number sentence also changes. To hide and reveal the number sentence, click on the box with the question marks. You can replace a number in the number sentence with a question mark by clicking on the number, and drag counters around the screen to form groups. Addition can be changed to subtraction by clicking on the addition sign in the box. Counters can be dragged into the displayed box, which you can make opaque to hide the counters.
The ITP can be used to model addition by combining and counting, and subtraction by partitioning and taking away. The hide and reveal options allow you to pose questions with unknown numbers in different positions in the number sentence. Partitioning counters in different ways helps children to identify all sums and differences of numbers to 20.

The controls also allow you to move 1 or 10 beads to the left or right of the string to show addition and subtraction. This ITP can be used to model different counting and calculation strategies.

ITP Difference
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 allows you to compare two rows of beads and to analyse the calculations they can represent. It can be used to promote the language of addition and subtraction, particularly the interpretation of difference. The ITP operates as a series of animations which show how the rows of beads can be represented by two number lines and then as a single number line with the difference indicated by a ‘jump’.
