Day 18: Least Common Multiple, Greatest Factor Test

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 solutions of problems.

The Learning Objective: Find the least common multiple of two or more numbers, find the greatest common factor of two or more numbers, apply the rules of divisibility for 2, 3, 4, 5, 6, 9, and 10, and define the rules of divisibility for 2, 3, 4, 5, 6, 9, and 10

Quote of the Day: "Anytime I find myself drifting into a negative mindset - and this happens to everyone - I realize that I'm on the road to failure. And more often than not, the way out of that mindset is to get back to work." - Rick Pitino

Agenda:

1. Take the quiz
2. Start the weekly quiz
3. Explain our homework which is to go online and sign in to the online textbook then answer a question using Google Forms to prove that the student got on the online textbook.
4. Clean out the binder
5. Connect Four (not the Connect Four you think)

The Assessment: The quiz, Connect Four

Homework: Use the online text then answer this question.

My Glass Half-Full Take: We had a fire drill today and it went very well. At the beginning of the year I told all of the students that emergencies and how we prepare for them are the most important thing that we can do in a school day. I brought up the example of Newtown, Connecticut on that first day of school although we didn't discuss it in great detail, but just to drive how the point of how potentially dangerous and serious a situation could be. It is easy for the students to respond the way that they should right after I give that speech but that was seventeen school days ago. Today it appeared they got the message. Everyone knew where to go and understood once we got outside to listen for me to call off the attendance.

One Thing to Do Differently: I only got to Connect Four in one out of three classes and I find this assignment to be excellent on a number of different levels. It gets students out of their seats, gets students to be social, is a formative assessment, and involves the type of collaboration that I'm pretty certain will contain a math focus. It could have been useful to do this a day earlier in the last five minutes of class.

Link of the Day: I liked this game for teaching place value of decimals, comparing decimals, and getting students to think strategically about decimals. Way more engaging than having them memorize place values.
