Day 10: Rules of Divisibility

6th Grade Math Standards: 6.NS. Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Learning Objective: Multiply multi-digit factors to find a product.

Quote of the Day: “As it turns out, the more types of relationships a person has the less susceptible they are to developing a full-blown cold, even after direct exposure to a cold-causing virus. When people have a wide range of connections, it provides them with a sense of psychological security that buffers them from day-to-day stress. And because they experience stress less often, their bodies are better conditioned to fend off physiological challenges when they occur.” – Ron Friedman

Agenda:

1. Self-Assessment from the Operations Quiz
2. QSSQ
3. Rules of divisibility notes
4. Rules of divisibility song
5. Rules of divisibility pepper
6. Rules of divisibility practice

Assessment: Pepper, Self-Assessment, homework practice

Glass Half-Full Take: I tried to shorten the notes today. I originally had the definitions for prime and composite numbers in the notes but cut them out. The divisibility rules themselves are enough for most of these students and really require memorization. I also took out example problems from the notes and just used the homework problems as examples because it lessened the homework load while still giving me the opportunity to offer feedback. Less is more.

Regrets: I wish I provided a chart that shows every student in the class their grade on the first quiz because I list all grades in fraction form to make students do the decimal conversion all year. Eventually they adjust, but for now it would be good to keep us moving if I eased this transition.

Homework: Divisibility Practice

Link of the Day: Great game for teaching least common multiple. Fizz Buzz.
