Example 1
Grandma's Special Chocolate Chip Cookie recipe, which yields
4 dozen cookies, calls for 3 cups of flour. Using this
information, complete the chart:
Table‐Create a chart
comparing the
amount of flour
used to the amount
of cookies.
Table‐ Is the
number of cookies
proportional to the
amount of flour
used? Explain.
Unit Rate‐What is
the unit rate and
what is the
meaning in the
context of the
problem?

Closing:
1.) What points are always on the graph of two quantities that are
proportional to each other?
2.) How can you use the unit rate to create a table, equation, or
graph of a relationship of two quantities that are proportional to
each other?
3.) How can you identify the unit rate from a table, equation, or
graph?
