Bubble Pop - Multiplication Bubble Pop - Multiplication

A fun way to help children learn their multiplication tables. Choose which times tables to practise and then try and pop all the bubbles before your time is up. Try and make the target number (at the top) by shooting a multiplication bubble. So if your target is 10, and you have the x2 bubble, you will need to hit 5, as 5 x 2 = 10.

The free demo version has 10 missions to complete; the full version (for registered users) has 70 missions. The game is ideal for playing on a tablet or phone. Encourage your class to play at home and then watch their confidence and fluency grow.

Balancing Calculations Balancing Calculations

Find the missing number to balance the calculations. An excellent tool for reinforcing an understanding of the role of the equals sign. Choose one objective, or many. You can choose all the objectives for a single year group (or multiple year groups). You can also choose to balance between different types of calculations (eg subtraction and division)

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 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.
