Link: Materials for Describing a Process

I was doing a Google Image search for materials for describing a process, and found useful diagrams on two websites here and here.

I've put them on a Google slideshow presentations (slides, pub) and on a Google Doc (docs, pub).  I've also included an activity in on the Google document in which the steps are cut up, and then shuffled, and the students have to put them in order.
These diagrams are suitable for Writing IELTS Task 1 -- describe a process, or for practice with the present passive.
