New York State Common Core Math Module 1, Grade 6, Lesson 17
Lesson 17 Outcome
• Given a rate, students find ratios associated with the rate, including a ratio where the second term is one and a
ratio where both terms are whole numbers.
• Students recognize that all ratios associated to a given rate are equivalent because they have the same value.
Lesson 17 Summary
• A rate of 2/3
gal/min corresponds to the unit rate of 2/3 and also corresponds to the ratio 2:3.
• All ratios associated to a given rate are equivalent because they have the same value.
NYS Math Module 1 Grade 6 Lesson 19 Classwork
Analyze tables, graphs, and equations in order to compare rates.
Examples 1–2: Creating Tables from Equations
1. The ratio of cups of blue paint to cups of red paint is 1:2, which means for every cup of blue paint, there are two
cups of red paint. In this case, the equation would be red = 2 x blue or r = 2b, where b represents the amount
of blue paint and r represents the amount of red paint. Make a table of values.
2. Ms. Siple is a librarian who really enjoys reading. She can read 3/4 of a book in one day. This relationship can be
represented by the equation days = 3/4 books, which can be written as d = 3/4 b, where b is the number of books
and d is the number of days.
1. Bryan and ShaNiece are both training for a bike race and want to compare who rides his or her bike at a faster rate.
Both bikers use apps on their phones to record the time and distance of their bike rides. Bryan’s app keeps track of
his route on a table, and ShaNiece’s app presents the information on a graph. The information is shown below.
a. At what rate does each biker travel? Explain how you
arrived at your answer.
b. ShaNiece wants to win the bike race. Make a new graph to show the speed ShaNiece would have to ride her
bike in order to beat Bryan.
2. Braylen and Tyce both work at a movie store and are paid by the hour. The manager told the boys they both earn
the same amount of money per hour, but Braylen and Tyce did not agree. They each kept track of how much money
they earned in order to determine if the manager was correct. Their data is shown below.
Braylen: m = 10.50h where h is the number of hours worked and m is the amount of money Braylen was paid
a. How much did each person earn in one hour?
b. Was the manager correct? Why or why not?
3. Claire and Kate are entering a cup stacking contest. Both girls have the same strategy: stack the cups at a constant
rate so that they do not slow down at the end of the race. While practicing, they keep track of their progress, which
is shown below.
a. At what rate does each girl stack her cups during the practice sessions?
b. Kate notices that she is not stacking her cups fast enough. What would Kate’s equation look like if she wanted
to stack cups faster than Claire?
