Grade Level7th/8th
Week #Week 20 Jan. 18-21
Unit of InstructionUnit 7 Radical Expressions and Exponents
Standard(s) Taught

MAFS.912.N-RN.1.1 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.

MAFS.912.N-RN.1.2 Rewrite expressions involving radicals and rational exponents using the
properties of exponents.

MAFS.912.N-RN.2.3 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 product of a nonzero rational number and an irrational number is irrational.

MAFS.912.N-RN.1.2 & MAFS.912.N-RN.2.3
Simplify exponent and radical terms that are being multiplied and divided. Identify as rational
and irrational. (continued from previous day
