“Board Slam” is another name for the math game that is at the heart of the National Number Knockout, which you can read about here. The game is played on a six by six grid of numbers. Three dice are rolled. The student must incorporate all three numbers that are rolled, employing addition, subtraction, multiplication, division, roots, and exponents, in such a way that the result is a number on the board. All three numbers must be used once, but cannot be used more than once. If more than one numeral one is rolled, the student is given an automatic re-roll. As the student generates equations to solve for each number, they cross the number off of the board. Students are given sixty seconds to generate as many equations as possible with unique answers.
