Objective

SWBAT: • Create and describe a ratio between two quantities • Calculate a unit rate • Use rate reasoning to solve problems • Use ratios to convert measurements • Find a percent of a quantity as a rate per 100

Big Idea

If the stores have equivalent prices, what do you know about n? Students review for the Unit 5 test by completing stations.

Do Now

5 minutes

See my Do Now in my Strategy folder that explains my beginning of class routines.

Often, I create do nows that have problems that connect to the task that students will be working on that day.  Here I want students to think about what they have learned throughout the unit.  I have students share out with the class.

Review Stations

30 minutes

Notes:

  • Before this lesson I use quiz data to Create Homogeneous Groups.
  • I will start off working together with these students to focus on topics in the review that they need help on.  I may omit some problems for these students so that they can focus on quality, instead of quantity.

There are many ways to do stations.  Today I Create Homogeneous Groups.  I identify which stations groups need to focus on first.   I set out the copies of the stations throughout the room.  I Post a Key for each station somewhere in the classroom.  I review expectations for the day.

Students are engaging in MP1: Make sense of problems and persevere in solving them, MP2: Reason abstractly and quantitatively, and MP6: Attend to precision.  Groups can move at their own pace, each time they complete a station, they check in with me.  I quickly scan the work.  If they are on track, I send them to check their answers at the key.  If I see repeated mistakes I circle the problems and have them return to work on them.  Once they have successfully completed a station, they check it off on their To Do List and move on to another station.

 

At the end of the work time, I hand around several staplers for students to staple their completed station worksheets together.

Closure

15 minutes

For Closure I show them the two rates.  I explain that Hidden Sweets charges $0.50 per ounce of candy and Sugar Heaven charges $ n for each pound of candy.  I ask students what they know about n if both stores have equivalent prices.  Students participate in a Think Write Pair ShareI call on students to share out their ideas.  I want students to remember that there are 16 ounces in one pound.  If they forget that fact, I tell them.  Therefore, Sugar Heaven must charge $8 per pound.  Students are engaging in MP7: Look for and make use of structure.

Then I present a second situation.  I tell students that Sugar Heaven’s price is 10% cheaper than Hidden Sweet’s prices.  What must n equal if this is the case?  Again students participate in a Think Write Pair Share.  I call on students to share out their ideas. Some students may take the equivalent rate of $8 per pound and take 10% off.  Other students may start with the cost of $0.50 per ounce and take 10% off and then find the price per pound.

Students pass in their completed station work.  For Homework, I tell students that they need to complete the stations that they did not finish.  If some students have not completed a large amount, I will give them an extra day or two to complete the work.
