Day 57: Decimal & Percent Conversion

6th Grade Math Standards: Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.

The Learning Objective: Convert decimals to percentages

Quote of the Day: The odds of a perfect game being thrown in baseball (one in twenty thousand) are far smaller than the chance you will be struck by lightning in your lifetime. But a perfect game is precisely what Detroit Tigers pitcher Armando Galarraga had happening one early June evening in 2010. He’d recorded twenty-six consecutive outs and had gotten the twenty-seventh batter to tap a weak ground ball to the first baseman, tagged the bag ahead of the runner and got ready to celebrate. There was only one problem: the umpire, Jim Joyce, swung his arms wide and shouted “Safe!”

When he got back into the umpire’s locker room, Joyce immediately cued the game video and watched the play – only once. He saw how badly he’d blown the call. But instead of letting the dust settle in silence like so many of his colleagues, Joyce chose a different path. He walked straight to the Detroit Tigers locker room and requested an audience with Galarraga.

Face red as a tomato, and tears in his eyes, he hugged Galarraga and managed to get out two words before dissolving into tears: ‘Lo Siento.’

About 16 hours later, the Tigers and Indians played again, but the meeting that mattered came before the game when Galarraga was tabbed for the trip to home plate to turn in the lineup card. Joyce was waiting for him. The two exchanged handshakes and hugs in one of the most inspiring, emotional, and moving displays of sportsmanship any sport has ever seen.” – Dale Carnegie  
Question from Yesterday (as always from a student): "Is that a fraction or a ratio?"

Assessment: Weekly quiz was given back to students corrected with highlights to fix problems that were wrong; my favorite no; homework examples; pepper responses

Agenda:

1. Jumpstart with number lines 
2. Collect WQ 
3. Visual Patterns #14
4. Pepper as students put problems on the board
5. Review homework
6. My favorite no convert 2/9 to a percent and 0.7 to a percent
7. Notes on decimals to percentages 
8. Work on the homework

Glass-Half Full: This is the most I have ever seen students correctly determine what 0.7 is as a percentage. It was also nice to see how students came up with 22% on my favorite no. Some divided and some just found equivalent fractions (multiplying 9 by 11). The repeating decimal part of is what was new for the students.

Regrets: Not going over the 13th problem on the homework was a mistake because many students got it right. It just was one of those things I forgot within the flow of the class.
