Mathematics  Common Core Standards
Ratios and Proportional Relationships  Grade 6
Understand ratio concepts and use ratio reasoning to solve
problems.

CCSS.MATH.CONTENT.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."

CCSS.MATH.CONTENT.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, so
there is 3/4 cup of flour for each cup of sugar." or
"We paid $75 for 15 hamburgers, wich is a rate of $5 per
hamburger."

CCSS.MATH.CONTENT.6.RP.A.3
Use ratio and rate reasoning to solve realworld and
mathematical problems, e.g., by reasoning about tables of
equivalent ratios, tape diagrams, double number line diagrams,
or equations.

CCSS.MATH.CONTENT.6.RP.A.3.A
Make tables of equivalent ratios relating quantities with
wholenumber measurements, find missing values in the tables,
and plot the pairs of values on the coordinate plane. Use tables
to compare ratios.

CCSS.MATH.CONTENT.6.RP.A.3.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?

CCSS.MATH.CONTENT.6.RP.A.3.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.

CCSS.MATH.CONTENT.6.RP.A.3.D
Use ratio reasoning to convert measurement units; manipulate and
transform units appropriately when multiplying or dividing
quantities.
