This document provides classroom materials on exponents including guide cards, activity cards, assessment cards, enrichment cards, and a reference card. The cards introduce exponents, ask students to identify bases and exponents, rewrite expressions without zero or negative exponents, simplify expressions using laws of exponents, and evaluate exponential expressions. The reference card reviews the general form of exponential expressions and laws for multiplying, dividing, and taking powers of exponential expressions.

3. GUIDE CARD Identify the base and the exponent. Rewrite the expressions without zero or negative exponents. Apply the laws of exponents in simplifying expressions.

4. “ Ignorance of the Law excuses no one”

5. Now……. If you perform operations on exponential expressions, then you should also consider the laws that governed it.

6. ACTIVITY CARD Read and analyze each item. 1. Identify the exponents and base of the following expressions : A. X 5 D. (1/2) 4 B. 4 2 E. y -5 C. a 3

7. NOW......lets try this one!!!!! Rewrite the expression with zero and negative exponents. 1. x-4 2. 1 x -3 LOOKS EASY huh ?

8. How about this? 3. 3x5y2 0 27x10y 64m -8 4mn -5

9. coool…..now check this out! 5 . (3a 2 ) 0 + 3 (a 2 ) 0 - 3a 0 (3a 0 ) -2 Awesome!!!!!!

10. You should try this too!!! Simplify the following expressions using the laws of exponents 1. -5a 4 (3a 7 ) 4. (6xy 5 ) 3 y 8 .y 5 5. 2a2 3 5n 5 m 6 3 n 8 m 6 perfect!!!!!!

11. ASSESSMENT CARD 1 Complete the table by identifying the base and exponent of the following expressions: I love this game! Expressions Base Exponents X 2 (-4y) 3 5x 6 11 2 8 5. (3-x) 2

12. Wanna try another one? Give the simplest form of the following: (a 2 b 3 ) 0 2. (-4a 3 b -2 ) -3 3. 2x 3 x 2 y a 2 -4 4. b 5. 3x 2 y 0 (18 x -3 y) -1 EXCELLENT !

13. ANSWER CARD Activity Card Exponent Base a. 5 x b. 2 4 c. 3 a d. 4 1/2 e. -5 y

14. 2. 3. a. 1/x 4 a. -15a 11 b. x 3 b. y 13 c. 1 c. 5/n 3 d. 16n 8 / m 9 d. 216x 3 y 15 e. -9 e. 8a 6 /3

15. Assessment Card answer key A. Base Exponent 1. x 2 2. -4y 3 3. x 6 4. 11/8 2 5. 3-x 2

16. B. 1. 1 2. b 6 -64a 9 3. 8x y 3 4. b 4 a 8 5. x 5 6y Wish to have some more? I love math…

17. Let’s get some more fun…..

18. ENRICH YOUR MIND….. Simplify the following:

19. Wooaah!!!you are great! Check this out…… 1 2 (a + b ) -1/2

20. You are doing a really good job!!! Give this one a try…..Evaluate: 4y -2/3 when y = 8 + 3y 1/3 + 2y 0 Found the answer?

21. How about this one now? 10 3 + 10 2 + 10 1 + 10 0 + 10 -1 + 10 -2

22. REFERENCE CARD

23. One last look……… Exponential notation is considered a mathematical shorthand as it allows an expression to be written more concisely. For instance, 7.7.7.7.7 is written as 7 5 . The general form of the exponential expression is x n and indicates that x is to be used as a factor n times.

24. To multiply expressions of the form a m , remember that for any numbers a and b , and positive integers m and n : a m .a n = a m+n Product Powers (a m ) n = a mn Product of a Power (ab) m = a m b m Power of a Product (a m b n ) p = a mp b np Power of a Product a m = a m where b ≠ 0 Power of a b b m Quotient

25. Congratulations!!!! You Made it! 1 st Place Bravo!!!
