I show teachers how to use an app throughout the learning process and to take students through Bloom's taxonomy:
Use the app number line: https://itunes.apple.com/app/number-line/id319589184?mt=8
First have students just use the app, and ask if this alone helps students to learn and practice the content?
THEN, show how the app (and other mobile tools) can be used differently:
1) Teacher models the app and their thinking with the class during formal instruction.
2) Students work in pairs (driver/navigator or toucher/talker) to explain their thinking and play the game together
3) Students use the video camera and paper numbers to create a video explaining how they put the numbers in order.
4) Teacher has students take a google quiz to assess individually.
This experience is typically a total wake up call for teachers about the potential of mobile devices.
