Day 33: Ratios Intro

6th Grade Math Standards: 6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

The Learning Objective: Define ratio; give an example of a ratio

Question from Yesterday (as always from a student): What was Jeanine's rate of putting together calculators for one hour?

Assessment: Students stood on their own when they were done a problem and were either checked by me or a classmate. Students also journaled their results of the decimal quiz and put a date that they would make up the quiz if they were unsatisfied with their results.

Agenda:

1. Record and reflect on the decimal quiz. I asked the students to write how they studied, how long they studied, a question that they have, and what day/time they will make up the quiz if they are unsatisfied.
2. Review the decimal quiz
3. More depth to the ratio notes (you can write them three ways, highlight the words before and after "to" in a word problem two different colors. Student copy and my copy
4. Rip out and start the homework from the textbook. 

Glass-Half Full: The notes this year were revamped. I included a problem that was released from the MCAS a year or two ago.

I also liked the idea of making students write a date out that they were going to be retaking the decimal quiz because I have not done this before and this made them slightly more accountable than they have been in the past.

Regrets: I have always used an exit ticket with this lesson and only did so in one of my three classes this time around. It could lead to homework being done in an unsatisfactory manner, which means that homework would be pointless tonight.

Link of the Day: National Council of Teachers of Mathematics is looking into changing a high school model of math that is largely broken. Here is the announcement from the NCTM president Matt Larson.
