While reading Maniac Magee with a small group, I decided to focus on 8 words only while reading. Even though we discussed other unknown words as we read.
Attached is a blank template for student's to write the "kid friendly definition," part of speech, and a sentence using the word.
There is also a definition page with the answers I gave to students who didn't have good definitions.
Editable if you'd like to add or change words.
