At first glance, this might be a little mundane compared to the sort of tasks I normally share.

This task was designed for some consolidation with a class who had done some work on this topic, but were not yet secure. There is some deliberate variation sequences built in, such as in the first 3 questions and in questions 14 to 18. I have used reversed divisions (questions10 and 13) in several places . There are many misconceptions which can arise from and be addressed as a result of engagement with this resource. So, while it looks like a boring worksheet there is a significant amount of thought and structure to the question choice.
