Mangahigh just launched their fully-integrated COMMON CORE standards as a core part of their game-based math curriculum. It's FREE to sign up!
You could play the games as a whole class activity on your IWB
The SMART Notebook app for iPad enables students to open their own version of a SMART Notebook lesson on their iPad and take it with them, wherever they go. Now students can work with the same SMART Notebook file – individually on their iPad and then collaboratively in class on the SMART Board interactive whiteboard.
Teach pattern, maps, ordinal directions, graphing and more with Isle of Tune. Students can work together to create a giant island of tunes on the IWB, then work individually on their own.
Could be used with IWB to create a timeline as a class and record learning. Free basic account. Paid accounts allow you to share your timeline creation.
