If the last post whet your appetite for this type of puzzle, then the screenshot below presents you (or your students) with another challenge. Can you make 533?
I showed the online video to my year 9’s today and they went for it. I played it up a bit and claimed that I had fallen in love with Lily. I showed her bio on the whiteboard and tried to break down the stereotype of a “Maths nerd”. Onto the video and the kids were busy trying to get the target numbers! A worthwhile way to spend the last 20 minutes of an afternoon class, since the students were engaged right up to the bell!
