by:
Tonya Petty

2. QUICK WRITE
Write whatever you know about exponents on a sheet of paper. (Take 3 minutes.)

3. PARTNER UP
Discuss your findings with your partner. Then bring back to whole group.

4. OBJECTIVE(strategic teaching agenda)
The students will be able to use powers and exponents in expression.
Alabama Course of Study: 6:1

5. VOCABULARY write on back of Washing Machine GO.
exponents
tells the number of times the base is used as a factor; also called an index/indices
OR exponential notation
Number written as a base number with an exponents (numbers expressed using exponents)
powers
Numbers expressed using exponents
base

6. or exponential notation X n base exponent power
Bonjour my friends!! This expression is called a
power or
exponential notation

7. Evaluating powers (write on GO)2 3
exponent
base
Identify and read the Power or Product.
3 to second power or 3 squared
2. Identify the base and exponent.
What does the power or product mean?
mulitply 3 times itself 2 times.
Evaluate the Power or Product.
3 x 3 = 9

8. POINTS TO REMEMBER (Write on the bottom of your GO.)
When no exponent is given, it is understood to be 1.
Any number raised to the power of 1 will always equal the number itself.
Any number raised to the power of 0 (except for 0) will always equal 1.

9. EXAMPLE 1
Write 45 as a product. Then find the value of the product.
1. A Power; Four to the fifth power.
2. 4 is the base; 5 is the exponent.
3. The power means 4 times itself 5 times
4. 4x4x4x4x4 =

10. EXAMPLE 2
Write 3 x 3 x 3 x 3 using an exponent. Then find the value of the power.
1. A Product; 3x3x3x3.
2. 3 is the base; 4 is the exponent.
3. The product means multiple 3 times itself 4 times.
4. 3x3x3x3

OUR TURN

12. EXAMPLE 3 4 3
= 3 x 3 x 3 x 3 1 81
EXAMPLE 4
25 x 25
= 252 2
625

13. now
y'all turn
with a partner

14. Get with your
9 o’clock buddy

15. Write each product using an exponent. Then find the value of the power.
EX5: 2x2x2x2
EX6: 6x6x6

16. Now….Get with your
6 o’clock buddy

17. Write each power as a product. Then find the value of the product.
EX7. 26
EX8. 37

18. now
your turn

19. 1) 46
2) 9 x 9
3) 43
4) 11 x 11 x 11
5) 41 =
6) 40 =

20. Evaluate each power or product…..
1) 46 = 4•4•4•4•4•4 = 4096
2) 9 x 9 = = 81
3) 43 = • 4 • 4 = 64
4) 11 x 11 x 11= = 1,331
5) 41 = 4
6) 40 = ?
