Accessible math. Using a Livescribe pen - questions can be read to students. They can record their mathematical thinking aloud, no writing. QR codes allow pre filmed word problems to be accessed when needed. Cool for all, invaluable for us! QR code generator
Using a "Makey Makey" - create a shape sorting game. When you place the shape in the correct location you hear all the attributes of that shape. Students study concepts while coding the game and then again while playing.
