QR code puzzle worksheet
Here’s an idea that’s been bubbling away in my head for a while. This version of it is far from the best way of doing it I suspect but I wanted to get the idea out there so others can start to adapt it.
Basically, I’ve made a QR code and then transferred it pixel by pixel to excel. I put numbers in some of the squares and then created quick sums based on whether the square originally was filled or not.
After that, I’ve just emptied all of the ones that had a number in and were coloured.
Finally, I’ve made the text a light grey and the grid in a pale, dotted grey so that they don’t interfere with the QR reader.
I recommend doing it yourself first so you can check that the final result will be readable by whatever reader will be being used.
Enjoy and let me know what you think.
