Unit 1: Ratios and Rates
Possible time frame:
13-15 days
The concepts of ratio, rate, unit rate, and percent are introduced in this unit. Students extend their understanding of fractions to include the ratio of two quantities and use ratio
language to describe the relationship between the quantities. Students apply their understanding of equivalent fractions to create tables of equivalent ratios, find missing values
in the tables, and plot the pairs of values on the coordinate plane. Students also focus on the rate per 1 (unit rate) and the rate per 100 (percent). Students solve real-world
problems involving unit rates and percents.
Major Cluster Standards
Understand ratio concepts and use ratio reasoning to solve problems.
6.RP.A.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The
ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received,
candidate C received nearly three votes.”
6.RP.A.2 Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio
relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar.” “We
paid $75 for 15 hamburgers, which is a rate of $5 per hamburger.”
Standards Clarification
6.RP.A.1 Students continue to
use the concepts of ratio as
they use multiplication and
division to solve real-world
problems.
6.RP.A.2 Unit rates are limited
to non-complex fractions.
6.RP.A.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios,
tape diagrams, double number line diagrams, or equations.
a. Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the
pairs of values on the coordinate plane. Use tables to compare ratios.
b. Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then
at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?
c. Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving
finding the whole, given a part and the percent.
Focus Standards of Mathematical Practice
MP.1 Make sense of problems and
persevere in solving them.
MP.4 Model with mathematics.
MP.5 Use appropriate tools
strategically.
MP.7 Look for and make use of
structure.
The content standards for this unit require that students make sense of real-world and mathematical problems (MP.1) by modeling
relationships with ratios (MP.4) using a variety of tools strategically (e.g., equivalent ratios, tape diagrams, double number line
diagrams, or equations) (MP.5). As students work with unit rates and interpret percent as a rate per 100, and as they analyze the
relationships among the values, they look for and make use of structure (MP.7).

Sample End of Unit Assessment Task:
Taylor and Anya live 63 miles apart. On some Saturdays, they ride their bikes toward each other's
houses and meet somewhere in between. Taylor is a very consistent rider - she finds that her speed is
always very close to 12.5 miles per hour. Anya rides more slowly than Taylor, but she is working out and
is becoming a faster rider as the weeks go by.
1. On a Saturday in July, the two friends set out on their bikes at 8 am. Taylor rides at 12.5 miles
per hour, and Anya rides at 5.5 miles per hour. After one hour, how far apart are they?
2. Make a table showing how far apart the two friends are after zero hours, one hour, two hours,
and three hours.
3. At what time will the two friends meet? How do you know?
4. Taylor says, "If I ride at 12.5 miles per hour toward you, and you ride at 5.5 miles per hour
toward me, it's the same as if you stay still and I ride at 18 miles per hour." What do you think
Taylor means by this? How do you know if she is correct?
5. A couple of months later, on a Saturday in September, the two friends set out again on their
bikes at 8 am. Taylor rides at 12.5 miles per hour. This time they meet at 11 am. How fast was
Anya riding this time? Justify your answer.

3. At what time will the two friends meet? How do you know?
At 3 hours, Taylor and Anya only have 9 more miles to travel before they meet. The miles
between Taylor and Anya decreases by 18 miles per hour. Since 9 is half of 18, it will take onehalf hour to travel the 9 miles, so they will meet 3.5 hours later, at 11:30.
Alternate answer: Since the distance between Taylor and Anya is decreasing at 18 miles per
hour, 63/18 = 3.5 hours, so they will meet at 11:30.
4. Taylor says, "If I ride at 12.5 miles per hour toward you, and you ride at 5.5 miles per hour
toward me, it's the same as if you stay still and I ride at 18 miles per hour." What do you think
Taylor means by this? How do you know if she is correct?
Taylor is correct and what she really means is that the distance between them is decreasing by
18 miles every hour, so the amount of time it will take them to meet is the same as if one person
stays put and the other rides at 18 miles per hour. However, the place they meet will not be the
same.

At 0 hours the friends are 63 miles apart, and at 3 hours they are 0 miles apart. The friends are
getting closer at 21 miles per hour. Since Taylor is riding 12.5 miles per hour, Anya must be riding
8.5 miles per hour.
Alternate Response: Students could also determine that Taylor rode 37.5 miles in the three hours
(12.5 miles per hour x 3 hours) which would mean that Anya has to ride 25.5 miles in three hours
(63 miles – 37.5 miles). 25.5 miles/3 hours = 8.5 miles per hour. This is Anya’s rate.

Include a narrative explaining your choices with justifications for those decisions in your final
product. Be prepared to share your narrative with the class.
Sample Response:
We recommend the following to be purchased for the end-of-year crawfish boil based on 150 people:
• At a rate of 3 pounds of crawfish per person, we need to buy 3 x 100 = 300 pounds of
crawfish. At $2.75 per pound, the cost of the crawfish would be 300 x $2.75 = $825.
• If 3 pounds of corn and potatoes feeds four people, then 1 person will eat 0.75 pounds of
corn and potatoes. For 100 people, this would mean 100 x 0.75 = 75 pounds of corn and
potatoes. The cost for the corn and potatoes will be 75 x $1.50 per pound = $112.50.
• Based on our group preferences, we decided that we would order enough water for 50
people, coke products for 30 people, and tea for 20 people. If each person drinks at least two
beverages, then we will need to buy at least 100 waters, at least 60 coke products, and
enough tea for 40 drinks.
o Waters come 24 to a case, so 100/24 is about 4.2 cases, but since we can’t buy a
part of a case, we will need to buy 5 cases. 5 cases of water at $6.00 per case will
cost $30.
o Coke products are packaged 12 per case, so to get 60 coke products we will need 5
cases because 60/12 = 5. 5 cases of coke products at $4.50 per case will cost $22.50
(5 x 4.50 = 22.50).
o To have enough tea for 40 drinks, we will need to have 4 gallons of tea (40/10 = 4).
We suggest buying 2 gallons of sweet tea and 2 gallons of unsweet tea. The cost of 4
gallons of tea can be found by multiplying 4 x $10 which gives a cost of $40.
o The total cost for the end-of-year celebration is found by adding the total costs of
each of the menu options: $825 + $112.50 + $30 + $22.50 + $40 = $1,030.00. To find
the total cost per person, divide $1,030 by 100 people, and the cost per person is
$10.30.
