Activity Alert: Crack The Code

Jul 21, 2023

 

Combination lock puzzles have become popular ways to use detective skills in number problems! These games provide clues for you to work out the codes (or, combinations of numbers) that successfully open a lock. And today, we’re sharing our Mathnasium version for you and your child to have some maths fun!

So, are you ready to crack the code? Download our number lock puzzle (below) to get started with your child! We recommend going in order, as the puzzles increase in difficulty. Take your time and have some fun, mathematical debates over the options for each number. When you think you’re done, check your answer by making sure each clue satisfies your code number, then compare it with our answer key. Do your best to use only mental maths!
