Download Mad Minute Activity - Simplifying using laws of exponents

Mad Minute for Laws of Exponents
Algebra 091 (Bill Monroe)
Primary Concept:
Simplifying expressions using laws of exponents.
Purpose:
Students will demonstrate their ability to identify appropriate rules for simplifying expressions using the laws of
exponents..
Supplies:
paper, pencil, activity sheet, room, normal setting, students working individually
Vocabulary:
Base, exponent, power, factor, variable factor, numeric factor, product rule for like bases,
Prompts and time considered:
Prompt
5 minutes
Give basic instructions
Students working individually; given 10 problems on activity sheet (from easy to hard). After
instruction, students have 1 minute to identify and align with type of factoring. (See activity
sheet)
Prompt # 1
5 minutes
You will work alone and answer as many of the 10 questions on the activity sheet
as possible.
Prompt #2
Hand in to instructor (name required), no grade given.
Prompt #3
5 minutes
Discussions on problems (next class day) – hard or easy?
Prompt #4
5 minutes
Students work in pairs on the hard problem to identify the type of factoring then
solve the problem and prepare to present to the class. Take the hardest problem to factor. Find
the method and complete the factorization (do in groups of two).
Total time:
20 minutes
Note:
Good factoring methods for Quadratic Expressions will get solutions to Quadratic Equations in
the next lesson.
