Unit 6: Exponents and Polynomials
25 days
Insert unit priority standards(s) below (include numerical and letter codes). Underline the
skills (verbs) students must master and circle the concepts (nouns) that students need to
know.
1) A-APR.A.1: Understand that polynomials form a system analogous to the integers,
namely, they are closed under the operations of addition, subtraction, and multiplication;
add, subtract, and multiply polynomials.
2) A-SSE.A.2: Use the structure of an expression to identify ways to rewrite it.
3) F-IF.C.8b
Write a function defined by an expression in different but equivalent forms to reveal and
explain different properties of the function.
b. Use the properties of exponents to interpret expressions for exponential functions. For
example, identify percent rate of change in functions such as y = (1.02)t,
y=(0.97)t, y=(1.01)12t, y=(1.2) t/10, and classify them as representing exponential
growth or decay.
4) F-LE.A.1c
Distinguish between situations that can be modeled with linear functions and with
exponential functions.
c. Recognize situations in which a quantity grows or decays by a constant percent rate
perunit interval relative to another.
Insert unit supporting standards in italics below (Include numerical and letter codes)
1) N-RN.A.1
Explain how the definition of the meaning of rational exponents follows from extending the
properties of integer exponents to those values, allowing for a notation for radicals in terms
of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want
(51/3)3 = 5(1/3)3 to hold, so (51/3)3 must equal 5.
2) N-RN.A.2
Rewrite expressions involving radicals and rational exponents using the properties of
exponents.
3) N-RN.B.3
Explain why the sum or product of two rational numbers is rational; that the sum of a
rational number and an irrational number is irrational; and that the productof a nonzero
rational number and an irrational number is irrational.

4) A-SSE.B.3a
Choose and produce an equivalent form of an expression to reveal and explain properties of
the quantity represented by the expression.
a.Factor a quadratic expression to revealthe zeros of thefunction it defines.
5) F-IF.C.8a
Write a function defined by an expression in different but equivalent forms to reveal and
explain different properties of the function.
a. Use the process of factoring and completing the square in a quadratic function to show
zeros, extreme values, and symmetry of the graph, and interpret thesein terms of a context.
