If you are looking for bright, colourful worksheets and resources for very young children then urbrainy.com is one site you must visit. They have launched the first of their interactive maths games this week. The site is developing into an excellent resource with plenty of free stuff for young children beginning their understanding of maths. I like the layout, which is bright and modern looking and it seems to be developing by the week.
Subscription for a year is well worthwhile at just £10.00 and I believe that schools can subscribe for a site licence for just £12.00 a year.
