There are some great established educational resources out there which are gradually being migrated to the iPad. Once such tool is eChalk which has been around for at least ten years but was originally, like many resources, written all in flash and therefore would not work on a mobile device.

eChalk, if you haven't heard of it, is a global teachers' favourite online resource with interactive activities and games, some resources are free but most are accessed via a school subscription. It is mainly used in our school by Maths and Science (I believe) but it would be great to know if other subjects also find it useful since it now covers many curriculum areas.
