CRACK THE CODE · GRADE 3
Roblox Mermaid and Unicorn Code Breaker
Calculate the value of each mythical symbol to unlock the hidden blox treasure chest.
Each shape stands for a number. Work out the missing ones first, then solve the shape equations and read off the 4-digit code. Do it here or print the sheet — the answer key comes with it.
The key
Every symbol is a whole number from 1 to 12. A number in front of a shape means multiply: 2 stars = 2 x star.
Find the missing values
Some shapes in the key are missing. Use these equations to work them out, then write them into the key. Take them in order.
