I could not find any post asking for advice on maths equipment so I could be in totally the wrong place - apologies in advance for that. Here is my question, in case I am in the right place ....
My son has bought at least 4 pairs of compasses but he says they always move whilst he is trying to draw his angle. He might not be the most dextrous of children but there must be a 'best' pair of compasses or dividers out there. He has a very important exam coming up and I'd really like to get him something that won't add to the stress of the situation.
I'd be very grateful for any recommendation(s) and/or advice.
