THE NUMBER VAULT™ — FILE 006

THE 83-YEAR-OLD SECRET 🔐

83 YEARS. TEN MATHEMATICAL CHALLENGES. ONE FORGOTTEN SECRET.

For 83 years, a mysterious vault has remained sealed.

Nobody remembers what was placed inside. All that remains is a collection of numerical clues left behind by its last Keeper.

THE VAULT IS LOCKED. THE CODE IS HIDDEN. THE CHALLENGE IS ON!

Welcome to The Number Vault™ — where mathematics becomes an adventure in codebreaking!

In File 006, learners become junior codebreakers tasked with solving ten mathematical challenges involving addition, subtraction, multiplication, division and powers.

But there's a twist!

Each answer must be matched to a secret code key to reveal a letter. Only by solving the calculations can learners uncover the mysterious ten-letter code.

And once the code is cracked?

The mystery continues!

Learners must imagine what might have been hidden inside the vault for 83 years, illustrate their discovery and explain why someone would have wanted to keep it secret.
