I had forgotten just how good this website is! There is loads of clipart to use in your own worksheets and presentations and also for the pupils to use in their work. Finding good quality clipart that you can use freely is just so hard – well take a look at the work Phillip Martin has done and you wont be disappointed. He has even included free PowerPoint templates to help you get your creative juices flowing!
