LEA: Construct and compare linear
and exponential models and solve problems
Standards:
 LEA.1. Distinguish between situations that
can be modeled with linear functions and with exponential functions.
 LEA.1.a. Prove that linear functions
grow by equal differences over equal intervals, and that
exponential functions grow by equal factors over equal
intervals.
 LEA.1.b. Recognize situations in which
one quantity changes at a constant rate per unit interval
relative to another.
 LEA.1.c. Recognize situations in which
a quantity grows or decays by a constant percent rate per unit
interval relative to another.
 LEA.2. Construct linear and exponential
functions, including arithmetic and geometric sequences, given a
graph, a description of a relationship, or two inputoutput pairs
(include reading these from a table).
 LEA.3. Observe using graphs and tables
that a quantity increasing exponentially eventually exceeds a
quantity increasing linearly, quadratically, or (more generally) as
a polynomial function.
 LEA.4. For exponential models, express as
a logarithm the solution to ab^{ct} = d where
a, c, and d are numbers and the base b
is 2, 10, or e; evaluate the logarithm using technology.

 Lesson set:
Distinguish
between linear functions and exponential functions: This is a
series of seven video lessons that also include guided practice on this
topic. Videos demonstrate how to model exponential growth
situations with 2 variables; how to determine the end behavior of a
polynomial or exponential function, and the greater of two polynomial
functions; how to compare polynomial and exponential growth; name the
3rd ordered pair belonging to a linear or exponential function. Aligns
with LEA.1.
 Lesson set:
Prove how linear
functions grow (and exponential functions): This is a series
of two video lessons that also include guided practice on this topic of
how linear and exponential functions grow. Aligns with LEA.1.a.
 Lesson set:
Prove that,
over equal intervals, linear functions grow by equal differences
and exponential functions grow by equal factors. Five
video lessons: Identify linear functions by linking equal
differences to equal intervals, graph an exponential function,
understand the rate of change in exponential functions,
distinguish between linear and exponential functions by
examining intervals and using tables. Aligns with
LEA.1.a.
 Lesson set:
Recognize when
one quantity changes at a constant rate per unit interval of
another. Four video lessons: Compare relationships
between quantities using linear models, interpret d=rt by
graphing its linear function, find average rates of change using
data in tables, calculate average rate of change using d=rt.
Aligns with LEA.1.b.
 Lesson set:
Understand exponential growth and decay: This is a series
of four video lessons that also include guided practice on this topic.
Videos demonstrate writing exponential growth and decay functions,
determining which of two growing quantities will exceed the other at a
given point in time. Aligns with LEA.1.c.
 Lesson set:
Recognize when
one quantity grows or decays by a constant percent rate per unit
interval of another. Four video lessons: Graph
depreciation and halflife of an element using an exponential
decay model, graph the spread of behaviors using an exponential
growth model, compare exponential growth models using graphs.
Aligns with LEA.1.c.
 Lesson set:
Express
solutions to exponential models as logarithms; evaluate using
technology. Five video lessons: Evaluate logarithms
using exponentials, solve for time in a continuously compounding
function, solve realworld problems using properties of
logarithms, use an exponential formula to solve a population
problem, solve a halflife model. Aligns with LEA.4.
MIT BLOSSOMS: Video lessons with additional teacher
and learner resources. Descriptions are from the video summaries.
 Flu Math Games:
"This video lesson shows students that math can play a role in
understanding how an infectious disease spreads and how it can
be controlled." Additional simulations are included.
Aligns with Algebra standards SSEB.3.c and REIA.1; Function
standards IFC.8.b, BFB.4.a, and LEA1.(a, c); and Statistics
and Probability standards IDB.6.a, ICA.1, ICB.4, CPA.2, and
MDA.1.
 Free Fall: "This video lesson is an example of "teaching for
understanding" in lieu of providing students with formulas for
determining the height of a dropped (or projected) object at any
time during its fall. The concept presented here of creating a
chart to organize and analyze data collected in a simple
experiment is broadly useful." Aligns with Function
standards IFB.6, IFC.7.a, LEA.1.a, and
Algebra standard CEDA.2.
 The Power of Exponentials, Big and Small:
"Exponential growth is keenly applicable to a variety of
different fields ranging from cell growth in biology, nuclear
chain reactions in physics to computational complexity in
computer science. In this lesson, through various examples and
activities, [the presenters] have tried to compare exponential
growth to polynomial growth and to develop an insight about how
quickly the number can grow or decay in exponentials."
Aligns with Algebra standards SSEB.3.c and CEDA.2 and Function
standards IFA.3, IFC.7.(a, c, e), IFC.8.b, and LEA.1.(a, c).
 The Towers of Hanoi: Experiential Recursive Thinking:
"This lesson is about the Towers of Hanoi problem, a classic
famous problem involving recursive thinking to reduce what
appears to be a very large and difficult problem into a series
of simpler ones. The learning objective is for students to
begin to understand recursive logic and thinking, relevant to
computer scientists, mathematicians and engineers."
Aligns with Algebra standard SSEB.3.c, and Function standards
IFC.8.b and LEA.1.a.
 Tragedy of the Commons:
"This lesson introduces students to the “Tragedy of the
Commons,” an extended metaphor for problems of shared
environmental or manmade resources that are overused and
eventually depleted. In this metaphor, shared resources are
compared to a common grazing pasture, or “commons,” on which any
dairy farmer can graze as many cows as he/she wishes. If too
many cows are added to the commons, they will overeat the grass
in the pasture and the shared resource will become depleted – a
disadvantage to everyone. In this lesson, students will be
inspired to think about possible solutions to this problem."
