Unit 5 Review Stations
Lesson 20 of 21
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
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.
- 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.
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 Share. I 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.
