SMP, Periodic Table Notes Check HW answers on the side board. Record correct answers in RB & turn in HW. 2. Jigsaw  Report to your colored groups and BEGIN your PT teachback.  Present (teach) your information to the group FIRST! This NOT a silent lesson – use your “6 inch” voices to teach the other members.  Complete the section of notes cooperatively. Ask your questions to ascertain clarity.  By Day 2, everyone in the group should have the Teachback WS completed and the follow-upo questions started. Cooperation and diligence is necessary….. I will be watching and listening. TODAY: PT Day 1

Today: PT Day 2 1.Continue with your group teach back then proceed to answer/check questions # Transfer answers to the sheet provided.  Answers to the outline are on my website for YOU to review this evening. 2.Transfer #’s to the scantron. On the scantron write Periodic Table Teachback 3.Due Thursday: BOTH the answer sheet, scantron, and each member’s research notes. 4.Group Quiz THURSDAY SMP, Periodic Table Notes 20142

Today: PT Day 3 1.Transfer #’s to the scantron beginning with # 46 on the scantron. Record all group members names in the name section. In the subject area, write PT Teachback. 2.Group quiz – each member should record his/her answers on their own quiz paper. I will collect one random quiz to score. Work together. 3.Transfer quiz responses 1-21 to the same scantron. 4.Submit the following: 1.Answer sheet 2.Scantron (#1-21 and #46-74 recorded) 3.Each member’s research notes.
