Questions to consider during Phase 0
What skill, content knowledge or mindset is necessary to
be successful with phase 0?
What do you think your teachers will have the most
difficulty with?

Big Ideas of the Unit
An expression in one variable defines a general calculation with the
variable representing the input and the expression calculating the
output. Choosing a variable to represent the output creates an equation
in two variables.
A linear equation in one variable can have one solution, no solution, or
infinitely many solutions. A linear equation in two variables has an
infinite number of solutions.
When two quantities, x and y, vary in such a way that one of them is a
constant multiple of the other, a model for that situation is y=kx where k
is the constant of proportionality or the constant ratio of y to x. An
equation is proportional if it includes the point (0,0) and is a straight line.
Rates of change communicate critical information
about a linear relationship. Rates of change are
synonymous with unit rate for proportional
relationships.
Lines have a constant rate of change because the ratio of the rise to
run between any two points on a line is the same.
13
What Content Does this Exercise Build on?
In 7th grade, students learn to recognize proportional
relationships represented graphically, algebraically and
In tabular form. Additionally, they learn to describe the
unit rate as the Constant of Proportionality and
understand that proportional relationships are identified
by a unit rate.
Students build on a basic understanding of functions as
a means of representing a relationship between two
quantities. They have also just engaged with finding and
comparing rates of change given multiple
representations of these relationships (table, graph,
equation, and context) in the functions unit.
14
What does this content set students up for?
A solid understanding of proportional relationships and
unit rate grounds students’ understanding of rates of
change.
Applications of Rates of Change when working with
graphs, tables, equations and data sets
HS – Facilitating meaningful engagement with non-linear
relationships and limits and derivatives
15
Aims that support this learning
SWBAT graph proportional relationships, interpreting the
unit rate as the slope of the graph.
SWBAT determine if a relationship is proportional.
SWBAT compare two different proportional
relationships represented in different ways by
determining the unit rate (slope)
16
Content Standards
8.EE.B – Understand the connections between
proportional relationships, lines and linear equations
8.EE.5 – Graph proportional relationships, interpreting
the unit rate as the as the slope of the graph. Compare
two different proportional relationships represented in
different ways
8.F.4 – Construct a function to model a linear
relationship between two quantities. Determine the rate
of change and initial value of the function from a
description of a relationship or from two (x,y) values,
including reading these from a table or from a graph.
Interpret the rate of change and initial value of a linear
function in terms of the situation it models, and in terms
of its graph or a table of values.
17
Practice Standards
SMP1 – Make sense of problems and persevere in
solving them
SMP2 – Reason abstractly and quantitatively
SMP3 – Construct viable arguments
and critique the reasoning of others
SMP4 – Model with mathematics
SMP6 – Attend to precision
18
Key Points
Why – The unit rate is a building block to understand rate of
change; Unit rates can be the most efficient means of
comparison.
What –
• When comparing rates, using the unit rate allows you to
find the amount of a unit per every one of the other unit
• Different representations of a problem are better for
different circumstances
• Unit rate only applies to proportional relationships because
there are equivalent ratios of corresponding values
How –
• Calculate the unit rate using an equation
• Compare the unit rates given the problem’s context
The Exercise
Problem: Anna and Jason have summer jobs stuffing
envelopes for two different companies. Anna
earns $1.53 for every 17 envelops she finishes. Jason
recorded his earnings in the table to the right. Who
makes more from stuffing the same number of
envelopes? How can you tell?

The What of the Exercise
How does the problem align to the priority
standards, aims, and concepts of the unit?
The problem involves the comparison of two different
representations of relationships, both proportional, and a
justification of the conclusion of that comparison. This ties
directly to the prioritized aim “represented in different
ways by determining the unit rate/slope and graphing.”
21
The How of the Exercise
How are students applying the focal SMP(s) in this
problem?
SMP3 – Construct viable arguments and critique
the reasoning of others
SMP4 – Model with mathematics
22
Alignment to Exercise Criteria
Draws thinking towards mathematics to be used
and learned; is relatively narrowly focused on a
strategy, concept or skill
May be difficult or easy, complex or simple, but
never puzzling
The path(s) towards the solution is(are) often
apparent
