Algebra 1 Unit 1: Expressions, Equations, and Inequalities
|
Unit Driving Question
How can we manipulate information to help us solve real-world problems?
Essential Questions
-
How can we represent information symbolically?
-
How do we develop mathematical arguments/proofs for solving real-world situations?
-
How can we use related, but different representations to solve real-world problems?
|
Big Idea 1: Polynomial expressions can be simplified and evaluated.
|
OAS-M: A1.A.3.2, A1.A.3.4 |
Lessons and Additional Activities
Big Idea 1 Lessons 1-4 Overview (includes links to teacher notes and student activities)
|
Evidence of Understanding
Generate equivalent expressions using operations on whole numbers and exponents
Evaluate a polynomial expression
-
Evaluate a variety of algebraic expressions including absolute value, radicals (square or cube roots), or rationals for given values of the variables.
-
Understand how to reason and work with a non-standard operation.
|
Big Idea 2: Polynomial expressions can be written as factors.
|
OAS-M: A1.A.3.3 |
Lessons and Additional Activities
Big Idea 2 Lessons 1-3 Overview (Includes links to teacher notes and student activities)

Big Idea 3: Square and cube roots can be added, subtracted, multiplied, divided, and simplified.
|
OAS-M: A1.N.1.1, A1.N.1.2 |
Lessons and Additional Activities
Big Idea 3 Lessons 1-4 Overview (includes links to teacher notes and student activities)
Additional Collaborative Activity:
Stations Activity: Radicals and Irrational Numbers- Students will work in collaborative groups to complete station activities providing opportunities to develop concepts and skills related to simplifying radicals, performing operations with radicals, and classifying and comparing rational versus irrational numbers.
|
Evidence of Understanding
Simplify square roots and cube roots
Perform arithmetic operations on square roots
|
Big Idea 4: Equations and inequalities can be solved in both algebraic and real-world contexts.
|

Evidence of Understanding
Solve equations and inequalities in real-world problems
-
Use knowledge of solving equations to solve real world problems such as angle measure, geometric formulas, or science and statistics problems.
-
Use formulas or other necessary equations to solve problems
-
Interpret solutions in original context to check for reasonableness
Solve equations with several variables in terms of one specific variable
Solve absolute value equations
-
Know that absolute value is a distance from zero and results in two solutions, one in each direction (positive and negative)
-
Isolate absolute value before solving equation
-
Recognize |x-a| =b is b units away from a since |x|=b is b units away from zero
-
Solve absolute value equations and interpret the solutions in the original context
Solve and graph compound and absolute value inequalities
-
Compound inequalities can have separate, or disjoint, solutions or overlapping, conjunction, solutions
-
Make connections between algebraic and graphical solutions
-
Graph solutions to inequalities on a number line.
-
Identify two separate inequalities of absolute value and determine outcome of their graphs
-
Write and graph compound inequalities given a real world situation
-
Use correct vocabulary of compound inequalities and determine number of solutions
