What's the first thing they do when you put them on-line?  Head for the interactive games?  Put them on this site and there is a wide choice of games (don't let on that they are using their maths though!) for them to choose from!  Lots and lots of information and other interactive areas too!

Ambleweb School's massive selection of fun and games for Maths (some of them can be teacher controlled).  Fast-loading and lots of variety.

Mike Kite's Interactive Numbers and Problems site - brilliant for introducing and reinforcing new ideas

Through Thorners School website (lots more interesting links here!)

Interactive adventure involving numberwork (and literacy of course!)

Just a bit of fun at the end of a lesson!  Try it - it made me laugh!

Simple shape recognition activity

Excellent page introducing and developing using money (and couldn't we all just do with that!)

Choosing the right furniture to fit your house!  Exploring shapes!  Excellent game!

Interactive Maths site which takes you through just about everything!

Get your students to practise their grid skills with this little game!

Excellent time-telling activity!

For those of us who find times tables an eternal problem, practise them here!

Simple shopping game to practise addition

Great maths game - well worth a go!

Not sure whether this is useful or not - converts fractions to decimals and vice versa - bit of a cheat really!

Make a maze and print it out - not sure if this is Maths or not but kids do love mazes and am sure there must be a link somewhere!

Wonderful "quiz" type site to compare numbers and symbols (you can choose)
