Disclaimer:
The following sample unit is intended to provide an example of a possible flow of instruction. Consider this a work in progress. As a
sample instructional plan, it should invite discussion and development. It is not intended to be prescriptive, only suggestive. It may
provide ideas and guidance in the development of conceptual understanding through a sample sequence of lessons. This UNIT can
be adapted, modified, expanded, delivered as-is, or not used at all. Lessons are not time bound and may extend beyond a day. It
simply provides an example unit of instruction which incorporates:


Integration of the 8 Mathematical Practices
Investigative tasks
Formative assessment and performance assessments
In this unit, you will find that specific standards are NOT listed within each lesson, as lessons integrate multiple standards to better
address conceptual understanding.
Previous Concepts
By the end of eighth grade, students have
learned to solve linear equations in one variable
and have applied graphical and algebraic
methods to analyze and solve systems of linear
equations in two variables. Unit 1 builds on
these earlier experiences by asking students to
reason quantitatively and use units to solve
problems. Students develop fluency writing,
interpreting, and translating between various
forms of linear and exponential functions and
use them to solve problems. Students will
analyze functions using different representations
and understand the concept of a function using
function notation.

Teacher Notes:
1. Keep in mind the Essential Questions, ten content standards, eight mathematical practice
standards when planning lesson outcomes for this unit. See Scope and Sequence and
Overview.
2. Use your warm-ups to frontload what is not taught explicitly in the lessons.
3. Academic Vocabulary Help
“Explicit Formula”
There are two ways to define functions, implicitly and explicitly. Most of the
equations are explicit equations like:
y = 2x-3 so that:
y = f(x) where f(x) = 2x-3.
But the equation 2x-y = 3 describes the same function. This second equation is an
implicit definition of y as a function of x. As there is no real distinction between the
appearance of x or y in the second form, this equation is also an implicit definition
of x as a function of y.
