AIM: How can we prepare for our unit exam on proportional reasoning? HW: Create a study guide with one sample problem from each topic Do Now: 1) A jacket is on sale for 70% off. Write an expression that represents the cost of the jacket. 2) The jacket originally costs $85. The tax rate is 8%. How much does the jacket cost after the discount, including tax? Announcement: Unit 2 exam on Proportional Reasoning will be Friday, December 1. Topics include: Unit Rates Solving Proportions for Missing Quantities Complex Fractions (and unit rates) Percent of Amounts (tax, commission, markup, tip, discount) Percent equations Rate tables/Graphs/ Determining proportionality from graphs, equations, and tables Writing equations to model proportional situations Classwork: Student reviewed topics from Unit 2.

AIM: How can we find unit rates involving complex fractions? HW: Finish Complex Fractions Unit Rate handout Do Now: Find the unit rate. 1. A bathtub fills at a rate of 20 gallons every 4 minutes. 2. You get paid $100 for eight hours of work. Announcement: Unit 2 exam on Proportional Reasoning will be Friday, December 1. Topics include: Unit Rates Solving Proportions for Missing Quantities Complex Fractions (and unit rates) Percent of Amounts (tax, commission, markup, tip, discount) Percent equations Rate tables/Graphs/ Determining proportionality from graphs, equations, and tables Writing equations to model proportional situations Classwork: We applied our knowledge of unit rates and proportional reasoning to tackle more difficult problems that involved fractions instead of whole numbers. For example: Find the unit rate in miles per hour if Jana rides her bike 12 miles in 45 minutes (3/4 hour). Resources:
Aim: How can we assess our understanding of ratios, percent, and proportional reasoning?
Homework: Enjoy time with your families! Happy Thanksgiving! Do Now: Please clear your desk of everything except for a pencil and a calculator Classwork: Unit 2 Quiz 2  Proportional Reasoning & Percent Announcements: Unit 2 Exam on Proportional Reasoning scheduled for next Thursday/Friday, November 30/December 1. Resources: Aim: How can we use scale factors, proportions, rate tables, and equations to find amounts of a mixture?
Homework: Prepare for quiz tomorrow Do Now: One group wrote f=2/3p and p=1.5f for Question A, part (2). Another group wrote f=1.5p and p=3/2f for the equations. How can you tell which group is accurate? Classwork: We looked at a problem in the context of a zookeeper that is in charge of feeding the chimpanzees at the zoo. The zookeeper needs to give the adult and baby chimpanzees different ratios of fiber to protein. We looked at how we could use proportional reasoning to solve a variety of situations. One of the focal points of today's problem is when the zookeeper accidentally make a mixture appropriate from the baby chimps when she should have made a mix for the adult chimps. We learned how to modify the mixture so that we could get it to the right ratio. Announcements: Unit 2 Exam on Proportional Reasoning scheduled for next Thursday/Friday, November 30/December 1.

HW: Comparing and Scaling Problem 3.3 PART A ONLY!! p.69 Do Now: 1.) A new pair of shoes cost the store n dollars. They markup their shoes 65%. Write two equations to represent the selling price, p. 2.) The shoes are ugly, so no one buys them for the selling price, p. The store puts them on sale for 30% off. Write two equations to represent the discounted price, d. Announcement: Classwork: In this Problem, the ratio of ingredients is given in percents. Students use rate tables, unit rates, equations, graphs, and proportions to answer questions about the mixture. Students fill in a table including both parttopart and parttowhole ratios. Sometimes they reason using parttopart ratios, and sometimes they use parttowhole ratios. Students think about one relationship by analyzing a graph. The power of a graph is that it shows many solutions for an equation. Students explore graphs further in the next Unit. Resources: AIM: How can we use proportions to find percents of amounts? HW: Discount, tip, markup, commission Worksheet Do Now: A pair of sneakers cost $85. They are on sale for 15% off. How much money will come off the price of the sneakers? Announcement: There will be a quiz Wednesday, November 23. Classwork: We explored the concepts of discount and tip today. We looked at scenarios around the upcoming Black Friday and Cyber Monday. We also looked at restaurant situations where diners are expected to leave a tip for service provided by waiters or waitresses. Students shared various methods to find percents, including shortcut methods that can be used without calculators. Resources:

HW: Comparing and Scaling pp.7778 #3538 Do Now: Michael buys computers, fixes them up, and resells them. He uses a standard markup of 40% of the buying price. If he bought a computer for $234, how much should he sell it for? Explain. Announcement: Classwork: We investigated a problem involving a used car salesman deciding where he should work. Two prospective employers offer two different ways to earn an income. The students used their understanding of markup, commission, and percents of numbers to determine which employer would yield a higher income. Resources: Part/Whole = %/100, where Whole is the amount of the item(s) and the Part is the portion of the whole (in this case, tax). AIM: How can we use proportions to find percents of amounts?
HW: Comparing and Scaling Problem 3.1 AB Do Now: Bob's Calculators buys calculators for $15. He marks them up 20%. What is the selling price of the calculators? Announcement: Classwork: We investigated a problem involving a used car salesman deciding where he should work. Two prospective employers offer two different ways to earn an income. The students used their understanding of markup, commission, and percents of numbers to determine which employer would yield a higher income. Resources:
