Numbers is a fantastic app that allows students to take their time and solve problems. The bubbles and fish element get users excited about making progress. The sensor that is placed on the top of the IPad records the numbers as they are placed, so if a student is attempting to place three 5s and one 2 to make 17, but they only place two 5s and one 2 down, the screen will read "12", and they can adjust accordingly.
How I Use It
I used Numbers for Osmo in an IPad makerspace station setup. The number pieces were spread out in front of the student so all combinations of addition possibilities were in plain sight.
