Have you ever asked students to define vocabulary words in a novel, only to have them copy down the first definition they find, whether or not it is relevant to the context of the sentence?
I have created these sheets to require students to justify the definition they chose, based on the context of the sentence in which the vocabulary word is found.
This is a 56-page, chapter-by-chapter vocabulary sheet set for The Secret School by Avi. The full product is 56 pages.
I would recommend either having students use a common class set of dictionaries, or requiring that they use a particular website to find definitions to allow for easier grading.
