Lovely interactive crossword on network theory taken form the now defunct www.ictgcse.com site. You might want to press F11 on your keyboard to make it more visible in your browser.
Series of tutorials using Impress (sorry for wrongly labelling this as Powerpoint previously) to create a quiz that uses triggered animations and sounds recorded by students. Ideal exercise for combining ICT with Languages. I must apologise to any French teachers in advance for me poor attempts at speaking the language!!
