## Developing strategic intervention materialPresentation Transcript

• Classroom Strategic Intervention Material Prepared by: Blaise Buquiran- Hobro SST1- JNHS, Talay, Dumaguete City, Philippines
• Guide Card
• Activity Card
• Assessment Card
• Enrichment Card
• Reference Card
• Percentage of Correct Responses
• GUIDE CARD
• Identify the base and the exponent.
• Rewrite the expressions without zero or negative exponents.
• Apply the laws of exponents in simplifying expressions.
• “ Ignorance of the Law excuses no one”
• Now…….
• If you perform operations on exponential expressions, then you should also consider the laws that governed it.
• 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
• NOW......lets try this one!!!!!
• Rewrite the expression with zero and negative exponents.
• 1. x-4 2. 1
• x -3
• LOOKS EASY huh ?
• 3.
• 3x5y2 0
• 27x10y
• 64m -8
• 4mn -5
• coool…..now check this out!
• 5 . (3a 2 ) 0 + 3 (a 2 ) 0 - 3a 0
• (3a 0 ) -2
• Awesome!!!!!!
• 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!!!!!!
• 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
• 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 !
• Activity Card
• Exponent Base
• a. 5 x
• b. 2 4
• c. 3 a
• d. 4 1/2
• e. -5 y
• 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
• A.
• Base Exponent
• 1. x 2
• 2. -4y 3
• 3. x 6
• 4. 11/8 2
• 5. 3-x 2
• 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…
• Let’s get some more fun…..
• Simplify the following:
• Wooaah!!!you are great!
• Check this out……
• 1 2
• (a + b ) -1/2
• You are doing a really good job!!!
• Give this one a try…..Evaluate:
• 4y -2/3 when y = 8
• + 3y 1/3
• + 2y 0
• 10 3 + 10 2 + 10 1 + 10 0 + 10 -1 + 10 -2
• REFERENCE CARD
• 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.
• 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
• Congratulations!!!!
