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.
-
(9+7) x 2 +11 = 43 (scores 8 points)
-
7 * 7 + 9 - 11 = 47 (scores 8 points)
-
(11+7) x 2 + 9 = 45 (hits the target and scores 10 points)
-
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.
-
(6+6) x (5-3) = 24
-
5! / (3! - 6/6) = 24
-
sqrt(6 x 6) x 5 - 3! = 24
-
(6+3-5) * 6 = 24
All of these solutions score 10 points. ​
DMAS (NEW GAME)
Use one row, column, or diagonal to hit the target 14 using division, multiplication, addition, and subtraction. As a team, students come up with these possible solutions in the 3 minutes allotted.​

Sample answers:
-
(8-1) x 2 = 7 x 2 = 14
-
4 x 2 + 6 = 8 + 6 = 14
​
both these answers are given 10 points!

Sample (incorrect) responses:
-
1 + 9 + 4 = 14​​​​ (must use 2 different operations)
-
2 x 8 - 1 = 16 - 1 = 15 (while this solution correctly uses two different operations it doesn't hit the target so no points are given D:)
SMASH
-
Your teammate sprints and gets the numbers 4, 7, and 2. Your team submits 4 x 2 - 7 = 1.
-
Then the teammate gets Ace, 3, and 9. You solve to get 9/3-1 = 2.
-
Next, you get 8, 8, 2; your team is stuck so you sprint back to get a new set of numbers.
-
You get 6, 10, 8, and find that (10+8)/6 = 3 works.
-
Repeat this process until time runs out!
