Day 20 Test Review, Open Responses & Prime vs. Composite

6th Grade Math Standards: 6.NS.4 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 least common multiple of two or more numbers in a real-world context

Quote of the Day: “As much as our culture talks about individual effort and self-improvement, deep down we revere the naturals. We like to think of our champions and idols as superheroes who were born different from us. We don’t like to think of them as relatively ordinary people who made themselves extraordinary. Why not? To me that is so much more amazing.” - Malcolm Gladwell

Assessment: The weekly quiz will be passed in tomorrow and checked by me. In circumventing the room today, students needed prompting in many cases.

Agenda:

1. Self-Assessment of the test
2. Journaling about the test
3. Review of the test 
4. Distribute the weekly quiz and review the directions
5. Let the students start the weekly quiz
6. Prime & Composite Number notes
7. Prime & Composite Number practice/homework
8. Continue working on the weekly quiz

Glass Half-Full Take: Repeating a factor always starts with one and itself several times. This is a concept that students will get at some point if they have not yet because of this slogan.

One Regret: It was hard to estimate the timing of everything today. I took almost a full block to review the quiz by the time I was through relating how the quote relates to the lesson, students had filled out their checklists, I showed pictures of common mistakes, etc. In the next block of class, I allotted 15 minutes to the weekly quiz being started. I could have allotted and 25 minutes and still had no issue working on prime and composite numbers.

I also had meant to reintroduce (or for many it would be a first introduction) the concept of numbers being relatively prime and forgot to do that today.

Homework: Prime & Composite number practice and the weekly quiz is due tomorrow as a rough draft since the students had time today in class.
