Puzzle: NRich Maths- Painted Cube Investigation

Great maths website: NRich Maths

10 05 2010

This is one of my favourite sites for getting resources for lessons and interesting homeworks. If you’re a student, there’s loads of maths puzzles and games to get you thinking as well as articles explaining interesting bits of the history of maths. If you’re a teacher, it’s an excellent site for getting enrichment based resources, many of which are interactive and work great up on the interactive white board. I use the puzzles on the site a lot to extend my more able pupils.

The site publishes a monthly ‘magazine’ which you can subscribe to by email and features new puzzles, resources and information about the site.

Check out NRich Maths and have some fun!
