My wife would probably allege that if the house were on fire my first priority would be to make sure the paper trimmer was safe. Not quite true perhaps, but it’s certainly true I do have a bit of an addiction problem. My cosy office is less than about 3 metres square, but it does hold five paper trimmers.
I make a lot of cards for number and sorting games for my pupils, and the other day I needed to convert a 24cm x 24cm card square from a cereal packet into 36 4cm x 4cm cards.
It seems intuitively obvious that some ways of cutting up the square will be more efficient than others, but in spite of my long experience I wasn’t clear what the best strategy would be.
Would it be best to (i) first slice the 24cm x 24cm square into six strips, or (ii) first cut the big square into quarters, or (iii) perhaps cut the big square into six 8cm x 8cm squares and then cut these up? Or perhaps another strategy is better than any of these.
Over to you. If you’re going to put yourself into my shoes I need to emphasise that I’m cutting card rather than paper, and my trimmer cannot handle more than one thickness. Do let me know how you get on with this exploration, which I’ve never seen offered anywhere else.
