For week 4, lesson 2, I had begun with a hocket inspired activity and then had the class perform an excerpt from the focus piece which focused on polyrhythms.
I decided that polyrhythms were too complex to chuck onto the end of a lesson so I have assigned an entire lesson (week 5, lesson 1) to polyrhythms now. I have designed a starter activity to introduce this musical technique which requires students to clap various combinations of the below polyrhythms.

I have provided this resource for teacher use only as I would teach these patterns to students aurally rather than showing them the notation. However, it could be shown to students after they have completed the activity to show them what the various polyrhythms look like in western notation.
With this change, students will also have more time to learn the polyrhythm arrangement and perform this as an ensemble.
I have also included practice melodic dictation questions from past HSC papers at the end of this lesson.
