This is an old site created by Bedfordeshire City Council Schools (2005). However, it contains free SMART Notebook documents and some Promethean flip charts. They are a good base to work with, to modify and add to as you need. There are SMART Notebooks for teaching literacy, science, history, art, numeracy, geography, languages and music.
