Maths games?

[parachutes]

Hello, can anyone recommend any decent maths games for ds (6)? I'm interested in all different types so any and all recommendations would be appreciated.
He has loved playing with things like 'Tell the time' by Orchard Toys and 'Travel the world' by ELC so I'm looking for something that uses addition/subtraction/multiplication etc in the games...or multiple games to cover the main topics.

Thanks.

Not sure if you would consider computer based games, but if you would I can't recommend this Timez Attack highly enough. It has been fantastic for helping my ds1 get his head around his times tables. It makes it more fun and interesting than learning by repetition.

You can watch a video about it on their website so you have a clearer idea of what the game is actually like and then if you like it you can download a free version here. You can use this to practise all the times tables, but only in one environment. If you pay for the whole game you can access different and more interesting environments and also keep records and jump about within the game more.

Ds1 is 7 and absolutely loves it. We have the free version at the moment, but he's asked for the full version for his birthday, as he's getting a bit bored of doing his tables in the dungeons, lol.

I think there is a book called Maths Games by peggy kaye - I dont own any of her books so I have no idea if it is any good

Thanks for the replies. I will have a look at both the suggestions.
