 AGENDA

1. Opening - active

2. Mini-Lesson – passive

3. 4 Corners – active

4. Review – active

5. IP - passive

6. Exit / Closing - passive

 ASSESSMENT

5 + 8(6 - 2)2 ÷ 4

1.  OPENING (8 minutes) ACTIVE

Have students answer mental math lesson coming in thru door.

Mixed Review Warm-Up (in Powerpoint). Include problems (8)(-6)

2.  Mini-lesson: CONTENT (10 minutes) PASSIVE

Do Q1:     5 + 8(6 - 2)2 ÷ 4

Teach students that I am only doing OPERATIONS inside parenthesis. If there was no OPERATION (+/-/X/div) visible, I would go to the E. When I see a number hanging out with another number outside parenthesis 8(16), I have to multiply.

Students fill out notes from this lesson.

3.  Guided Practice (30 mins) ACTIVE

1.   Two examples as partner practice.

2. You Try It / Show me 1 for A, 2 for B, 3 for C, 4 for D CFU

3. Try FIVE. Allow students to do five problems. Give answers. Fist to five to see how many correct.

4. Independent Practice (20 minutes) PASSIVE

Practice problems on back.

 5.  Exit Ticket and Closeout (8 mins) PASSIVE

Close out activity – 3,2,1 to identify the 3 new things learned, 2 old things remembered, and 1 question you still have.

Exit ticket, silent volume.

6. Reflection

 The GP CFU's were extremely effective for this lesson. They make it particularly easy to identify struggling students and to zone in on them during GP or even the beginning of IP to accommodate all learning styles.
