Lesson Plan : Multiplying Variables with Exponents
Teacher Name: | Proffessor Plum |
Grade: | Grade 9-10 |
Subject: | Language Arts |
Topic: | Multiplying variables with exponents |
Content: | Students will learn that when variables are the same and being multiplied, the exponents should be added. ie x^2*x^5=x^7. when variable and exponents are enclosed in parenthesis, the exponents must be multiplied. ie (x^5)^6=x^30. |
Goals: | Students will understand this |
Objectives: | I must be fun and down to earth and matter of fact so the students will feel that I understand them. |
Materials: | I will use the whiteboard and markers. when practice problems are answered correctly i will give them candy |
Introduction: | Hey class, my name is Richard, and if i don't show you guys how to multiply variables with exponents, I'm gonna fail my class. j/k, but that's what we're doing today. can anybody tell me anything they know about that or how to solve them? no? coo!! This will be no problem-o |
Development: | Start with x^2*x^5 and give steps to solving 1. make sure the base is the same (make sure they know what base is) 2.forget about the 'x' for "like one lil minute-he'll survive" and look at the exponents (make sure they know what those are. 3. add the exponents 4. don't forget the 'x'-"he's insecure and doesn't want to be a loser, so 5. re-unite him with his exponent buddy. ***give practice problems 1-5, then give these instructions*** 1.if parenthesis raised to exponents, then multiply. |
Practice: | 1. x^2* x^8=x^10 2. y^3* y^4=y^7 3.x*x=x^2 4.x^2*y^7= x^2y^7 ********* 5. (x^2)3=x^6 6(y^7)5=y^35 |
Accommodations: | Any Questions? Spend extra time with students who need it. |
Checking For Understanding: | Do u get it?!?!?! Random oral quiz. A Do now assignment in the morning. |
Closure: | I will start the next day with a small DO NOW activity. |
