Toot

I have an idea for a maths talk. I need information on an extremely important topic - whether clocks that have been rotated 180 degrees still look like real times! If you'd like to help, please click the survey link. You're very welcome to just answer one or two questions. But I think it shouldn't take more than a couple of minutes if you wanted to answer every one https://docs.google.com/forms/d/e/1FAIpQLScSW1e4vxb-kpZXYCvzDvOQtbtVG5Tz4HxNQ29m5Tz2hf0PTw/viewform?usp=sf_link

Most of them... If I saw them on a clock on the wall I'd make the assumption that there was something off with the alignment of the hands but I could have a good stab at what the time was.

Some would make me think that it was a clock where the hour hands only pointed directly at an hour marker, directly flicking from one to the next at some point (but that could be at half past, or it could be on the hour).

@TeaKayB Yes, there are definitely some children's books on telling the time where the hour hand is shown as being stuck exactly on the hour until it suddenly jumps to the next hour

Yes, I've seen that before. I was teaching someone to read an analogue clock recently, which I haven't really done before, and thinking back to being taught to tell the time myself with "and the little hand points at the 2..." type stuff, and thought 'but it doesn't unless the big hand is exactly on the 12!

I ended up talking about the little hand sweeping out the time over 12 hours, and then the big hand being there to give a more accurate idea of the actual minutes.

It's weird, because my memory of being taught how to tell the time is largely but not quite entirely gibberish. I'm not sure how I managed to figure it out in the end.
