This activity is a fun way to really make students think about vocabulary words. You know your students the best so choose words appropriate for them. I used all nouns from the book. I wrote them on cards and placed in a bag. Each student chose a card and that was their special word. I gave the students the directions and the rubric and I did an example for them. This was a take home assignment. It was fun to guess the answers to the riddles. I had students self assess on the rubric with a crayon, then I did my assessment with a pen. Final grade was sent home for parents to see and comment. This was a fun activity!
