This is a game for all you Big Spenders out there.

I will give you a sum of money and all you have to do is spend as much of it as you can aren't I generous?!

Your aim is to get as many items as you can and be left with the least amount of change.

Notes:
* The money is is English pounds, but that isn't a major issue
* You will need the Shockwave plug-in, available from the website.

You have to fill in the missing numbers in the equations to stop Harvey being catapulted into the distance. Simply click on a number to select it.

There are four ropes holding the catapult down, so you've got four chances. You'll see the ropes snap if you choose a wrong number.

From some problems, even at level one, this game at times requires logical reasoning and good number skills. Or luck. I really love this game, but it is better I think for students who already have good number skills.

Notes:
* You will need the Shockwave plug-in for this game. It is available from the website.

The computer will generate a number. To play, you simply drag and drop the arrow to where you think that number is within the range of numbers shown.

You'll get 3 lives for each question. If you get the answer right first time, you get 3 points, but every time you lose a life you lose a point. There are ten questions in each of the three levels, and you need 25 out of 30 to go up a level, so look after those lives!

Note:
* This game requires the Shockwave plug-in, available from the website.

The cruncher will randomly generate a number which pops into the machine. Once in the machine this number is either multiplied or divided by a surprise number

You have to predict what the correct answer is before the machine does! Good luck!

You have to find ways of using up to 4 numbers to match a target number exactly.

You don't have to use all the numbers - but you can use each number only once.

You can add, subtract, multiply, divide and even put them together.

Each level will vary the number of signs you can use and the choice of digits will be reduced to increase the difficulty.

Remember, there is always more than one way to reach the target number.

Notes
* You will need to have (or install) the free Shockwave Player.
* You can download the game from the website and run it as a stand-alone program
