GAME EXAMPLES

Hit the Target

Use 9, 2, 6, and 7 to hit the target 45. Four students come up with these possible solutions in the 90 seconds allotted.

  1. (9+7) x 2 +11 = 43 (scores 8 points)

  2. 7 * 7 + 9 - 11 = 47 (scores 8 points)

  3. (11+7) x 2 + 9 = 45 (hits the target and scores 10 points)

  4. T(9) * sqrt(11-7)/2 = 45, where T(n) indicates the nth triangular number (hits the target and scores 10 points)

24 Game

Use 5, 3, 6, 6 to make exactly 24. Four students come up with these possible solutions in the 90 seconds allotted.

  1. (6+6) x (5-3) = 24

  2. 5! / (3! - 6/6) = 24

  3. sqrt(6 x 6) x 5 - 3! = 24

  4. (6+3-5) * 6 = 24 

All of these solutions score 10 points. ​

SMASH

  1. Your teammate sprints and gets the numbers 4, 7, and 2. Your team submits 4 x 2 - 7 = 1.

  2. Then the teammate gets Ace, 3, and 9. You solve to get 9/3-1 = 2.

  3. Next, you get 8, 8, 2; your team is stuck so you sprint back to get a new set of numbers.

  4. You get 6, 10, 8, and find that (10+8)/6 = 3 works.

  5. Repeat this process until time runs out!
