I have used the last few chapters of the book for homework tests - it helped to test whether reading had been done in a class full of boys!
Chapters 18 - 23 tests all include teacher answers.The tests are quick and to the point using knowledge recall so you could use them in a number of ways with your class.
There are also a couple of other worksheets including:
1. Motifs - Daemons and Dust
Two part worksheet - your guide to daemons and dust!
A guide to the world Lyra lives in as the book opens, with accompanying activities.
