Updated resource and some misconception chat : Significant Figures

I’ve been busy touching up some resources when I teach with them, and adding them to TES.

Significant Figures : I updated this resource with a much greater emphasis on counting the significant figures before doing any rounding.

I did this after having a bit of nightmare with my year 7 class teaching rounding.

If you collect misconceptions, though, look at this that came up

This was really interesting to discuss and talk about with the student. There’s clearly a procedural understanding here, but not an understanding of what the procedure is trying to do. I made sure to reinforce this by talking about ‘is this closer to 700 or 800?’ but I had a thought. Maybe my procedure is stopping understanding here. Maybe I need to think about how I present examples in the future.
