An easy-to-use and entertaining site with high quality materials and resources for children and teachers. Each section offers worksheets, images and weblinks.
One of the first ports of call for planning history lessons; particularly since there are great ready-made lesson plans and activities! Like schoolhistory.co.uk there are loads of free downloads, useful resources and links.
Great English, Maths and Science IWB resources; my favourite of which is the insult generator - this can be used for work on adjectives, nouns and verbs. Some need to be purchased to access all features.
