Unit 7A - Anoka-Hennepin School District

Anoka Hennepin K-12 Curriculum Unit Plan
Department:
Elementary Math
Unit Title: Unit 7A - Exponents and Order of Operations
Grade Level: 5
Number of Lessons/Days: 11
Unit Summary: The purpose of Unit 7 is to investigate prealgebra concepts and skills. The key concepts are the notational conventions of
exponents, scientific notation, and number-and-word notation. They will develop rules for the addition and subtraction of positive numbers, and
learn to interpret number sentences. Students will be assessed through an end of the unit summative assessment.
DESIRED RESULTS (STAGE 1)
K-12 Program Understanding(s):
I. Students will understand that numbers can be used flexibly to solve various problems.
II. Students will understand that properties, patterns and relationships of numbers can be generalized into universal expressions.

Overarching Understanding(s) from Curriculum Map/Course
Understandings:
Students will understand that…
• identifying patterns and functions involving the four operations helps
to analyze, describe and extend patterns when developing rules to
represent and analyze change.
• the properties of arithmetic including the Distributive Property can
be generalized to many situations adding flexibility and fluency to
problem solving for an unknown and can be represented using
algebraic notation.
• data can be collected, organized and represented in multiple ways to
effectively analyze and communicate interpretations.
