No prob at all. One thing I did was ask them first “what do you find confusing about writing introductions?”. As they told me, I wrote the list on the board. Then I ticked off each one as we discussed it. This is actually a document we created in real time in class – not all of it (cause we ran out of time) but def the first bit about introductions and the bit where I explain that a paragraph is a bit like a sandwich (they found that really helpful as a memorable analogy). Best of luck with it – I def recommend that rather than just hand it out and read it, you first get them to articulate what it is they find confusing about writing introductions and what it is about the structure of a paragraph they don’t “get”, list them on the board and them cross them off as the ‘answers’ to these ‘confusions’ make things clearer.
