Okay, first we talk about the free ones ------ come on you know us ----- we like FREE!!!!! Educreations is a free app that turns iPad devices into interactive whiteboards and Evernote allows users to write lesson plans and upload them to mobile devices. Okay so now the not free ones but these sound ---- cool too! ---- Star Walk which costs $2.99 and allows students to see the location of stars on their iPads (like the two stars in the western sky that have been soooooo close are what planets?) and MathBoard which costs $4.99 and offers tools to improve math teaching and learning.
