Another math exercise

I stole this idea from the puzzle section of one of the UK’s national newspapers. The idea here is to fill in all the spaces in the centre block with the digits 1 through 9, some have already been done. It teaches kids how to think about what kind and size of answers certain combinations give. AND it’s good basic ‘order of operations’ practice.


I really enjoy doing these myself and so figured out a way to create my own using Excel. It’s much easier than it looks, although you have to be careful that you give enough ‘clues’. Filling in too many spaces ahead of time is not so much of a problem especially if the student is having trouble grasping the exercise.

Sadly, my students don’t enjoy doing them as much as I do but I thought I’d share this anyway.
