I have created Google Docs for each of the lessons in the first part of Unit 2 to track student work and encourage students to complete each step carefully. As they complete each puzzle they will screenshot their work and put the image in their notes. Not all lessons were formatted this way so these can be used for Lessons 3, 4, 6, 7, 8, and 9. Then they can submit the notes through whatever LMS your district uses. I'm still working on Docs for the rest of the unit and I will share them when I'm finished.
**I will have to make a few posts because it will only let me attach two links per post.
