Day 24: Prime Factorization Quiz

6th Grade Math Standards: Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4(9 + 2).
MA.4.a. Apply number theory concepts, including prime factorization and relatively prime numbers, to the solution of problems.

The Learning Objective: Find the greatest common factor of two or more numbers using prime factorization; determine if two numbers are relatively prime

Quote of the Day: “My mother was the greatest person in my life. She had an eighth grade education and cleaned floors at the Chicago Athletic Club for a living. Some of the greatest people in the world clean floors for a living. When you value everyone and treat everyone with respect, you may just be amazed at how they can make you better. Too often people will miss out on meaningful relationships with amazing people because they quickly pass judgment based on what that person does for a living, the clothes they wear, what kind of car they drive.” - Coach K

Question from Yesterday (as always from a student): "Why do we pronounce a number like two to the third power as two cubed sometimes?"

Assessment: The Quiz, the weekly quiz, and the decimals pre-assessment. I spent a lot of time correcting because what do teachers enjoy more?

Agenda:

1. Collect WQ #3 
2. Write no homework in the agenda books
3. Take the quiz
4. Sieve of Erastothenes when the students are finished
5. Decimals pre-assessment
6. Place value song 
7. Destination Elimination (if time) 

Glass-Half Full: After the pre-test, I know there are a handful of students that have the 4 operations down and can be challenged as a result. This will help let me differentiate so that these students are being pushed, but mainly it helps other students not get as rushed because I already know going in that they are going to need more time to comprehend.

Regrets: I wish that leading up to today's assessment more time was put into showing students examples of numbers that were relatively prime. I think it could have even been introduced the first day of greatest common factor. There were not enough examples and application, and too much emphasis on the definition.
