After Bell Work, students examined "47 Review and Lesson 51." The key is posted below. Students were given an extension to turn in this work today, which was first given to them on Wednesday, September 25, where they worked in groups for 20 minutes and were to finish this assignment by Friday. They had no other homework for the rest of the week.

After reviewing "Practice p.80-81," students began completing an error analysis for Unit 1 Test C. The following organizers were created in class for students to use for explaining and showing new work and solutions. For example, if the question asked for the greatest common fractor, students should provide an explanation similar to this one: "To find the greatest common factor, list all the factors for both numbers, then identify the largest factor that both numbers share." Sample explanations and work from various students for questions 21-24 were presented. Because I have a student who has been absent and has not taken the test, I am unable to post these samples at this time.

**Corrections are due tomorrow. I am available for tutoring in the morning and afternoon if help is needed.**## Tuesday, October 1, 2013 - Completing Tables and Graphing with Ratios, Finding Unit Rate

**Signed tests and corrections were collected at the start of class. Students who did not have it were instructed to complete this work for homework to turn in tomorrow.**

Students used equivalent ratios to complete tables and graphs using the following handout. When creating equivalent ratios, remember that all ratios will simplify to the same relationship. For example, the ratios 6/8 and 24/32 are equivalent because they both simplify to the relationship 3 to 4.

Rate and Unit Rate notes were completed (some classes will complete the distance formula portion tomorrow as it was not used in class today).

**Homework tonight involves completing Section A at the bottom of these notes (in addition to getting Unit 1 Test signed and corrections completed).** 2013.10.01_unit_rate_notes.pdf | |

## Wednesday, October 2, 2013 - Unit Rate Problem Solving and using the Distance Formula

I am still collecting corrections for the Unit Test. Deadline is this Friday. Homework tonight is to finish making corrections if it hasn't already been completed.

Rewriting the distance formula can be done using fact familes or using inverse operations and the multiplicative identity property. Please see the notes below.

## Thursday, October 3, 2013 - Problem Solving with Unit Rate

**Homework - "Lesson 7-2 #1-8."**Quiz tomorrow over ratios and unit rate. Please study vocabulary. Signed tests and corrections were collected at the start of class. Tomorrow is the last day to turn in corrections.

For question 1 of Bell Work, you can find the unit rate of each ratio in order to compare them, or you can do what these students did. Great thinking guys!

On the left, Austin saw that half of 32 is 16 and the sum of these two amounts equals 48. So he divided the cost of 32 fl.oz in half to find the value of 16 fl.oz, which was $0.82. He then added $0.82 to $1.64 for a sum of $2.46 - the cost of 48 oz using the rate of the 32 oz bottle. This showed him that the unit rate for the 32 oz bottle was more expensive than the 48 oz bottle. Therefore, the 48 oz bottle was a better deal.

On the right, Scott decided to make a table, listing the multiples of each bottle and the cost. At 96 ounces, he was able to compare the cost of each bottle finding also that the 48 oz bottle was the better deal.

__3rd Period Classwork Assignment:__After finishing "Problem Solving with Unit Rate #1-10" the class began "What's Faster than a Speeding Cheetah?" In this story, the speed of different animals and objects were illustrated. At the end of the book, students were asked to find how long it would take each of the animals and objects to get to the Moon. Isaac found the distance of the Earth to the Moon for us which was about 239,000 miles. Using calculators, students worked in groups to find the different times. In some cases, the answers were in the hundreds or thousands of hours. Did a number of hours that large make sense? Were these answers reasonable. Were there other ways to express time? Were some times better expressed in days, months, etc.?

__4th, 5th, and 6th Period Classwork Assignment:__Students completed "Problem Solving with Unit Rate #1-10." With these questions, students had to be flexible with unit rates. In some problems, they had to find the unit rate, then use it to answer the question.

## Friday, October 4, 2013 - Ratios and Proportional Relationships

Homework was checked before taking the quiz. Bell Work was organized in the following way:

(1) Ratio-Unit Rate Notes (handout given Friday)

(2) 9/30/13 - problems 1 and 2

(3) 10/1/13 - problems 1, 2, and 3

(4) 10/2/13 - problems 1-4, 6-8

(5) 10/3/13 - problems 1 and 2

Students used Bell Work and other notes on the quiz. After the quiz, students worked on "Unit Rate Practice" #1-10 located on the back of last night's homework. This assignment will be due during Quarter 2. Organized work should be stapled to the back of the worksheet.
