PUZZLE CARD 01
THE MAGIC SUM "V"
LOW-THRESHOLD HIGH-CEILING
Your team has been given five decryption keys represented by the numbers 1, 2, 3, 4, 5 . You must place exactly one number in each circular node of the V-shape so that the sum of the left arm equals the sum of the right arm .
Node A
Node B
Node C
Node D
Vertex
The Rule: Left arm sum (Node A + Node C + Vertex) must equal right arm sum (Node B + Node D + Vertex).
Threshold Mission: Find a configuration that works. What is the sum of each arm?
Ceiling Challenge: Can you find *all* possible sums? What makes a sum impossible? Prove it!
PUZZLE CARD 02
FOUR THREES (3, 3, 3, 3)
LOW-THRESHOLD HIGH-CEILING
The security mainframe requires code formulas for integers from 1 to 10 . You must use exactly four 3s and any combination of standard operators: +, -, *, /, ( ).
Decryption Examples:
To make 0 : 3 + 3 - 3 - 3 = 0
To make 6 : (3 * 3) - 3 = 6 ❌ Only 3 threes used!
To make 6 (Valid): 3 + 3 + 3 - 3 = 6 ✔ Valid!
Rule Check: You cannot use other digits. You cannot use square roots or factorials (unless your teacher grants permission!).
Strategy: Start with basic forms. How can you make 1 using two threes? \(3/3\). How does that help you build other numbers?

PUZZLE CARD 03
CRYPTIC SYMBOL SUMS
LOW-THRESHOLD HIGH-CEILING
A cryptic code locks the escape route. Use logic and arithmetic to find the values of ▲ (Triangle), ■ (Square), and ● (Circle) based on the row rules below.
▲ + ▲ + ▲
= 15
▲ + ■ + ■
= 11
● + ■ + ▲
= 12
Find individual values, then sum them up: ▲ + ■ + ● = SECRET COMBINATION

💡 For Puzzle 1: What happens if you place 5 at the vertex vs 1 at the vertex? Notice that the vertex is added to both arms, while the other numbers are only added to one arm.
💡 For Puzzle 2: Can you create the number 1 using two 3s? Yes: \(3/3 = 1\). Now, think: how can you write other targets by adding, subtracting, or multiplying ones? E.g., \(3/3 + 3/3 = 2\).
💡 For Puzzle 3: Start with the row that contains only one symbol. Row 1 states: \(▲ + ▲ + ▲ = 15\). Since all three triangles are identical, divide 15 by 3 to unlock the value of ▲ first!

SOLUTIONS & STRATEGIES
DECRYPT-KEY
Pedagogical Design: Low-Threshold, High-Ceiling
The three tasks inside this escape room are specifically modeled to reduce math anxiety while presenting meaningful mathematical rigor:
V-Sum Structure: Allows simple numeric trial-and-error (low entry). Progresses to structural algebraic constraints where vertex parity determines possible totals (high ceiling).
Four Threes Matrix: Students easily find small targets (1, 2, 3). Moving towards larger digits requires nesting parentheses, activating complex order of operations.
