THE NUMBER VAULT™ — FILE 008

THE 97-YEAR-OLD SECRET 🔐

97 YEARS. TEN MATHEMATICAL CLUES. ONE SECRET LOST TO TIME.

For almost a century, a mysterious vault has remained sealed.

Nobody remembers what was placed inside. No one knows why it was locked.

The only evidence left behind?

TEN NUMERICAL CLUES AND A CODE WAITING TO BE CRACKED!

Welcome to The Number Vault™ — where mathematics becomes a mysterious adventure!

In File 008, learners step into the role of junior codebreakers, tackling ten mathematical challenges involving addition, subtraction, multiplication, division and powers.

Each correct answer corresponds to a letter in a secret code key.

Solve the calculations. Match the answers. Reveal the letters.

UNLOCK THE MYSTERY!

But the adventure doesn't end with the final code.

Learners must use their imagination to illustrate what might have been hidden inside the vault for 97 years and explain why someone would have wanted to keep it secret.

It's a wonderful combination of mathematical practice, logical thinking and creativity!
