Comparing & Graphing Ratios 5-4
Working with your
partners, you complete the following ratio table for each frosting mixture. In
order to complete these accurately, you
had to listen to what the students’ frosting recipe called for as well as what
my teacher recipe called for.
After you have
completed the Drops of Blue column, label the third column that will show the
total number of drops for each relationship.
Then complete that column as well.
Whose frosting is
bluer? Whose frosting is redder? Justify your answers.

We then to use the
value from the ratio table for your frosting to create a graph in the
coordinate plane. Together, as a whole class we used the values in the table to
plot the points. Then connected the points and each of you discussed the graph
with your partners. What do you notice?

You explained the
relationship between the entries in the ratio tables and the points on the
graph. How is this graph similar to the first graph? How is it different?
How can you use
the graphs to determine whose frosting has more red or blue in it? You and your
partners discussed this question.
