Caution: Activities have answer keys at the end but you can edit them out after downloading. In the future the answer keys may be deleted. However, email me if you are a teacher for answer key if I delete the keys.

Grading recommendation for quicker grading. For students: less threatening, more fun, greater learning:

 

Have students share their work with the class. One way is to have them up load their work to a google slide and then have them support their answer. Discuss the validity of their support.
