Warm up involved using given statements and reasons and "assembling" a CPCTC proof. Worked on complicated, multi-part proof problems in small groups, will continue in next class with these tasks.
Homework
- finish p. 166 #12-16 if needed
- continue working on projects, due next Monday (can work on them in class Thursday or Friday)
- Assessment on triangle congruence proofs will be on Thursday or Friday

Warm up involved 2 CPCTC proofs without any guidance or partially filled out steps. Went over p. 166 homework then spent most of class finishing group work with multi-part triangle congruence proofs. Did a gallery walk where we examined others' posters and asked questions and made comments with post-it notes. Handed out practice/hw problems relating to proofs.
Handout from class
Homework:
-do #1-3 from handout in class
-assessment in class Thursday/Friday
-Bring project materials (camera/phone with photos, printed photos, laptop, transfer cable, poster/photo album, etc.) to work on in class Thurs/Fri
