This document contains a daily lesson plan for a math class with the following key points: 1. The lesson plan includes a warm up on finding the greatest common factor of two numbers, a corny joke, questions about an upcoming test, and introducing a new topic on prime factorization. 2. The lesson will cover finding the prime factorization of numbers using two methods - ladder diagrams and repeated division by prime factors. Examples are shown for factorizing 36 and 45. 3. Students will work in pairs to find common interests, discuss methods for solving the warm up problem, and work on finding the greatest common factor of various number sets using different methods including ladder diagrams.

1. Tuesday, August 16thComplete Warm Up

2. Write down HomeworkWarm UpWhat is the Greatest Common Factor of the following numbers:1. 24 and 32 2. 100 and 150

3. Corny Joke of the DayWhat did the Atlantic Ocean say to the pacific ocean?Nothing they just waved

4. When is the Test??!?!

5. “To the Computer & Beyond”What questions do you have?!?!?!

6. Finish Quiz Answer Sheet on topSilent read until everyone is finishedKeep folders up please 

7. Table of Contents ErrorPrime Factorization should say: pages 5 and 6 Musical Math Cards should say: Page 7

8. Table of ContentsDate: 8/16Section: 4-3Title: Greatest Common FactorPages: 8 & 9

9. Did you Know that there is another way to find Prime Factorization?!?!

10. Method 2Ladder DiagramDivide number by prime factors until the quotient is 1.

11. Just Watch Use a ladder diagram.Choose a prime factor of 36 to begin. Keep dividing by prime factors until the quotient is 1.336336121223642223231136 = 3 • 2 • 2• 336 = 3 • 3 • 2 • 2The prime factorization of 36 is 3 • 2 • 2 • 3, or 32 • 23.

12. You Try!Prime factorization of 45Choose a prime factor of 45 to begin. Keep dividing by prime factors until the quotient is 1.3455451593353531145 = 3 • 3 • 545 = 5 • 3 • 3The prime factorization of 45 is 3 • 3 • 5 or 32• 5 .

13. Which one do you like better?!?!

14. Getting to know your partner I want you to turn to the person sitting next to you and come up with at least 4 things that you both like  Are these commonalities more like: Factors or MultiplesWhat is one thing that we all like?

15. Question of the DayHow’d you solve today’s warm up?What is the Greatest Common Factor of the following numbers:1. 24 and 32 2. 100 and 150

16. Method 1: RainbowList all factors in a sequence and see which factor is the greatest2634

17. Method 2: Prime Factorization And 32

18. 45 18 2715 6 9Method 3: Ladder Diagram 45, 18, and 273Begin with a factor that divides into each number. Keep dividing until the three have no common factors. 3 5 2 3Find the product of the numbers you divided by.3• 3 =9The GCF of 45, 18, and 27 is 9.
