Bell Ringer

20 minutes

Students will sit in their individual think time seats to complete the Bell Ringer.  Students will have 10 minutes of I.T.T, Individual Think Time, to complete the 4 problems.  During this time, students should practice MP1, MP 2, MP4, and MP6.  Students should explain the problem to themselves, organize the important information, make sense of the problem, ask does the work make sense, change their work if it does not make sense, check their work and evaluate their work.  During this time students are working as individuals.

After the signal to transition to P.U.T time, pair up time, students should take 10 minutes to work with their table, designated group, or partner to discuss their thinking, strategies used, compare responses, defend their work, critique the work of their peer group, change any work from the mathematical discussion that took place.  Students will heavily rely on MP 3 during this time. Please refer to my strategy folder for questions you may ask to monitor understanding during this time. 

Whole Group Discussion

10 minutes

Once students have concluded their group discussion, please make sure students are leaving with the correct process in solving these problems.  Go over each problem with the whole group.  Have a few students share their strategies and thinking with the whole group.  Discuss common mistakes made that you found as you monitored for understanding. 

Students should correct any mistakes made on their own and be able to discuss why they made the mistake and what they now know from the whole group discussion.  

Exit Ticket

5 minutes

Students must identify one mistake they made and discuss what they did differently after the whole group discussion. Have students write their reflections on a separate sheet of paper and turn it into you before leaving for the next period.
