Finding Missing Number in Addition

Addition problem at the top of the screen with the second number blank.

In this program there is an addition problem at the top of the screen with the second number blank. The program voice says (for instance) “Ten plus what is sixteen? Click the correct answer.” There are four numbers at the bottom of the screen, and the student should click the correct choice from among them. If the student clicks the correct number, the voice says “Yes, ten plus six is sixteen.”
