Learning Benefits for Your Child - Subtraction helps your child understand that to
take away a number or deduct, he or she is subtracting. By understanding this
concept, your child will begin to apply his or her knowledge by solving problems.
ACTIVITY INSTRUCTIONS:
1. Slide the activity selector to “Subtraction.” You will hear
a short tune and a friendly voice will say “Pick a level.” In
this activity, all answers need to be inputted from right
to left.
2. In Level 1, the LCD screen will display square animations to
represent a numeric equation. The squares that are not
completely filled in are what are being taken away. The
solid squares are what you have remaining.
3. Next, a numeric equation that represents the squares
previously shown will be displayed. The unit will say “Input
your answer.”
4. If you answer correctly, you will hear “You’ve got it!” You
will then advance to the next question. If you answer
incorrectly, you will hear “Oops, try again!” The image
will be shown on the LCD screen and you will be able to
enter your answer again. If you answer incorrectly on
your third try, you will hear an incorrect sound effect
followed by “This is the answer.” The correct answer will
then be shown on the LCD screen.
5. In Levels 2 and 3, you will not be given the square
animations, only the numeric equations to solve.
