I had seen pictures like this before as it is the classic way of representing how the different types of number relate, but I wasn’t totally happy with any of the ones online.
So I decided to make my own.
I used this in a Year 10 Sixth Form taster session. I will post more about this later in the week.
I created this image in Geogebra because of how easy it is to draw ellipses and use LaTeX symbols. The file is available here.
