Teachers, save “Make your own subtraction video!” to assign it to your class.

You are all now teachers in your own academy! Think Khan Academy... except you are the expert! You are going to create a video teaching someone how to solve a subtraction problem using the standard algorithm. 1) Choose one of the problems on the board to solve. 2) Record yourself drawing out the steps of the problem on whiteboard. 3) As you write the steps, teach someone how to solve the problem using your voice to explain what you are doing. 4) Save the recording to your camera roll and upload it to this assignment. **Watch the Khan Academy video as an example, or if you need a refresher on subtracting!**
