Day 16: Least Common Multiple Word Problems

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 least common multiple of 2 or more numbers in a real-world context.

Quote of the Day: “Listening to others, evaluating - embracing - their opinions and creativity, may seem to suggest uncertainty and doubt about your own judgment and convictions. The ego gets in the way of your eyes and ears.” - John Wooden

Question from Yesterday: "Can we always multiply the numbers together to find the least common multiple?"

Assessment: Checking weekly quizzes and giving feedback; allowing students to work in partners on the homework to get feedback from a peer; checking yesterday's homework

Agenda:

1. Mystery number and homework was checked
2. Review the homework and mystery number
3. Hand back any papers (WQs, partner sheets, etc.)
4. Visual Pattern number three 
5. Least Common Multiple Notes 
6. Least Common Multiple Practice

Glass Half-Full Take: I enjoyed talking today about our star student and how he related to the quote of the day. We were celebrating students who made reference to other students in class when we were having mathematical discussions. This student always references what other students have said and builds upon or refutes those statements.

One Regret: I wish that I had put the students to task on the visual pattern as I was passing back papers. I want them thinking all of the time in class.

Homework: Six word problems on least common multiple (a few students were able to finish in class) and the Weekly Quiz #2.

Link of the Day: I like these pictures of 4 numbers to get students critiquing the arguments of others.
