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.
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.

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.
