Adding and Subtracting Seven
Skipping Your Way Through Addition and Subtraction
Adding and subtracting seven is just skip counting by seven. This workbook makes it easy by providing guidance from the telephone sequence. The martian telephone is almost the same as an earthlings phone except, the keys are rotated and the zero comes right before the three. This is a memory aid that helps the student skip count in sevens. It is the same tool we used for skip counting in threes, except we use it backwards since 7 + 3 = 10. With the aid of the martian telephone and the tens’ place indicator lights (which tell you which row on the keypad you are on) the student adds or subtracts seven by skip counting in sevens.
