Use this free mystery vocabulary sheet to launch your mystery unit. The worksheet also has students choose words from the books they are reading and write a summary of the chapter or book using as many words as they can. This is a great vocabulary building activity and is easily adapted to almost any grade level. I have students use the rephrase, connect and draw strategy with the initial list of words. I then have students complete the second page in book groups or it can easily be assigned for homework.
