Hi Mike,

Thanks for your answer!
The exercises are actually binary exercises but the children don't know.
All they know is a 'puzzle' to solve with pixelcoloring.
Funny I can solve it this way :-)
Still figuring how to do it because the children instruction is not just
binary writing as you explained it.

Did you see my picture?
