Learning Benefits for Your Child - Missing Sign allows your child to connect the
symbols of + (plus), - (minus) and x (times) with the operations of addition,
subtraction and multiplication. This activity provides an opportunity for your child
to solve problems using mathematical input devices by connecting a physical motion
with a conceptual idea.
ACTIVITY INSTRUCTIONS:
1. Slide the activity selector to “Missing Sign.” You will hear
a short tune and a friendly voice will say “Pick a level.” In
this activity, all answers must be entered through the
mathematical input devices.
2. In all three levels, you will see a numeric equation
displayed on the LCD screen. You will hear “What’s the
missing?” You will need to determine what operation sign
makes the equation correct and enter the sign with the
input devices. If you are correct, you will hear “You’ve
got it!” You will then advance to the next question. If you
are incorrect, you will hear “Oops, try again!” 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” and the
operation sign will be shown with the equation.
3. If by accident you select the wrong sign, you may enter
an additional sign instead of using the ERASE button.
