### Lesson Plan

 KEY POINTS / ESSENTIAL QUESTIONS

-        When working with ONE base and TWO powers, multiply the powers.

AGENDA

1. Opening - active

2. Mini-Lesson – passive

3. 4 Corners – active

4. Review – active

5. IP - passive

6. Exit / Closing - passive

 ASSESSMENT

What is the simplified form of the expression (x2)-10 ?

1.  OPENING (8 minutes) ACTIVE

Have students answer mental math lesson coming in thru door.

Adding and Subtracting Negative Numbers Warm-Up (available in this lesson)

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

Draw out exponent law and have students work together in small groups to figure out how to simplify. ("What is a power to a power") Students use notes sheet provided in this lesson.

3.  Guided Practice (30 mins) ACTIVE

1.   Example 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. Teacher works with students with less than 4 correct responses while the rest of students start on IP.

4. Independent Practice (20 minutes) ACTIVE

Practice problems on back of the notes provided in this lesson.

 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

To illustrate how this exponent law works, I drew out the exponent in long form within a set of parenthesis:

(x3)5   = (x . x . x)5  = (x . x . x)(x . x . x)(x . x . x)(x . x . x)(x . x . x) and then have students simplify.
