Tellagami on maths: Jacob S

This is a video on what I did to solve an addition problem with tenths in it. I needed to increase or decrease the value of one number to make it a whole number. Then I needed to decrease or increase the value of the other number by the same amount. I used tellagami to create this video. It is an application that can be downloaded from on an ipad. First I needed to pick a gender. Then I needed to pick a background. At last I need to record my voice.
