Don’t let your team into your own
Keep the opposing team from making touchdowns by setting up blockers in their path. Place blockers by building addition and subtraction problems whose sums and differences match locations on the football field.
Place blockers to keep the opposing team’s rushers from making it down the field to make a touchdown. The game is over once the opposing team makes 10 touchdowns. To place a blocker at a location create an addition or subtraction problem whose sum or difference is the same number as the number at the location. Note that some numbers will be randomly grayed out so that you can’t use them. To clear the saved high score go to the instructions page from the main menu and hit the Clear Data button.
