SSEA: Interpret the structure of expressions.
Standards:
 SSEA.1. Interpret expressions that represent a quantity in terms of its context.
 SSEA.1.a. Interpret parts of an expression, such as terms, factors, and coefficients.
 SSEA.1.b. Interpret complicated expressions by viewing one or more of their parts as a single
entity. For example, interpret P (1 + r)^{n} as the product of P
and a factor not depending on P.
 SSEA.2. Use the structure of an expression to identify ways to rewrite it.
For example, see x^{4 }– y^{4} as (x^{2})^{2} – (y^{2})^{2},
thus recognizing it as a difference of squares that can be factored as (x^{2}  y^{2})(x^{2} + y^{2}).

SSEB: Write expressions in equivalent
forms to solve problems
Standards:
 SSEB.3. Choose and produce an equivalent
form of an expression to reveal and explain properties of the
quantity represented by the expression.
 SSEB.3a. Factor a quadratic expression
to reveal the zeros of the function it defines.
 SSEB.3b. Complete the square in a
quadratic expression to reveal the maximum or minimum value of
the function it defines.
 SSEB.3c. Use the properties of
exponents to transform expressions for exponential functions.
For example the expression 1.15^{t} can be rewritten as
(1.15^{1/12})^{12t} ≈ 1.012^{12t} to
reveal the approximate equivalent monthly interest rate if the
annual rate is 15%.
 SSEB.4 Derive the formula for the sum of
a finite geometric series (when the common ratio is not 1), and use
the formula to solve problems. For example, calculate mortgage
payments.

concepts of factoring quadratic trinomials of the form ax^{2} + bx + c
where a=1.

MIT BLOSSOMS: Video lessons with additional teacher
and learner resources. Descriptions are from the video summaries.
 The Quadratic Equation: It’s Hip to Be Squared: "The lesson begins with three
quadratics and their graphs (three parabolas): y = x^{2} 
2x + (0 or 1 or 2). The prerequisite or corequisite is some working
experience with algebra, like factoring x^{2} 2x into
x(x2). The objective is to connect four things: the formula for
y, the graph of y (a parabola), the roots of y and the minimum
or maximum of y." Aligns with Algebra standards SSEB.3.a,
CEDA.2, and REIB.4.b and Function standards IFB.4, IFC.7.a,
IFC.8.a, BFB.3.
 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.

and Probability standards IDB.6.a, ICA.1, ICB.4, CPA.2, and
MDA.1.
 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."

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."
