There are 60 vocabulary words (broken down into 4 pages for each of the 5 parts of- Chapters 1-4, 5-8, 9-12, 13-17,18-22) of the novel The Lightning Thief by Rick Riordan. Each word has a sentence showing how the word is used in context in the book. The students fold each worksheet in half and make an educated guess or inference of the meaning of the word. After they make a guess for each word, they unfold the paper and read the actual definition. They can self-asses and check if their answer was close to the actual definition or not. This aligns with ELA Common Core Standard L.4, using context clues.
