Ratios and Proportional Relationships
Understand ratio concepts and use ratio reasoning to solve problems.
Standard(s)
6.RP.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.
6.RP.3a 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.
6.RP.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.”

Attributes of a Stink Bug
Each stink bug has 1 head, 2 body segments, and 4 legs.
Part 1:
Make a table showing the number of heads, segments, and legs for stink bugs. The table
should include 1 stink bug up to 10 stink bugs.
Part 2:
Draw a coordinate plane and plot the pairs of values on a coordinate plane for the number
of body segments on a stink bug from 1 stink bug up to 10 stink bugs.
Part 3:
Write about how you know that you have plotted the points correctly.

Attributes of a Stink Bug
Stink bugs are segmented creatures. Each bug has 1 head, 2 body segments, and 4 legs.
Part 1:
Make a table showing the number of heads, segments, and legs for stink bugs. The table should include all the
numbers from 1 stink bug up to 10 stink bugs.
Part 2:
Using the grid below, make a coordinate plane and plot the pairs of values on a coordinate plane for the number
of segments on a stink bug. Plot points for 1 stink bug up to 10 stink bugs.
Part 3:
Write about how you know that you have plotted the points correctly.
