Multipurpose Number (0-20) Generators

ELEMENATARY TEACHERS:

This multipurpose app displays a random number from 0-20 using colored chips.

Press the new number button to display a random new number.
Use the red, green, blue, and filling sliders to change the colors and filling of all circles (if you'd like).

You can use this app to have students immediately tell you what number is shown. You can also have students determine what needs to be added to the shown number to make a total of 20.
