The Westing Game is a fabulous mystery story - the best mystery book in print, in my humble opinion. With the CCSS focus on providing EVIDENCE for student thinking, this is a great jumping-off point for the whole year.
This literature unit includes an introductory vocabulary lesson/activity, comprehension questions (1 per chapter), a "Character Tracker" for guided reading concerning character development, and a prompt for a final writing piece (with grading rubric).
All activities have been aligned with the Common Core State Standards, which are noted on the cover page. Each comprehension question (in the teachers' information section) also identifies the CCSS it supports.
Student copies of the activities and comprehension questions are provided in an appendix.
