I recently showed my son some of them, but we adapted them in a few ways:
Here are some of the puzzles we tried:
This is 9 + 6 = 3, which is clearly wrong. However, moving just one stick will make it correct. Can you find which one to move?
… this makes it 9 – 6 = 3
We’re not going to give the answers for the following two puzzles:
Move one stick to make this correct
What is the smallest number of sticks you need to move to make this correct
It was fun trying to solve them and the fact that we could move the sticks around meant we could try lots of different ideas without worrying about being wrong.
We’ve put 6 of our favourite Roman Numeral puzzles (and all of the answers) into a pdf document, you can download it here:DOWNLOAD: Roman Numeral Stick Puzzles
