IN COLLECTION
In this unit, students will learn to build on their knowledge from Unit 2, where they extended the laws of exponents to rational exponents. Students apply this new understanding of number and strengthen their ability to see structure in and create quadratic and exponential expressions. They create and solve equations, inequalities, and systems of equations involving quadratic expressions. The five lessons (4.1-4.5) provide the instruction and practice that supports the culminating activity in the final unit project.

Lesson 4.1: Structure of Expressions and Equivalent Forms
by Kathleen DuhlLesson 4.1: Structure of Expressions and Equivalent Forms In this lesson students will focus on quadratic and exponential expressions. They will balance conceptual understanding and procedural fluency in work with equivalent expressions. For example, development of skill in factoring and completing the square goes hand-in-hand with understanding what different forms of a quadratic expression reveal.
Lesson 4.2: Perform Arithmetic Operations Polynomials
by Kathleen Duhllinear or quadratic in a positive integer power of x. They also extend their work on linear and exponential equations in Unit 1 to quadratic equations and to formulas involving squared variables.
Lesson 4.3: Solve Equations in One Variable
by Kathleen DuhlIn this lesson students will focus on polynomial expressions that simplify to forms that are linear or quadratic in a positive integer power of x. They will also extend their work on linear and exponential equations in Unit 1 to quadratic equations and to formulas involving squared variables.
Lesson 4.4 Solving Inequalities in one variable
by Kathleen DuhlLesson 4.4 Solving Inequalities in one variable Students should learn of the existence of the complex number system, but will not solve quadratics with complex solutions until Algebra II.
Lesson 4.5 Solve Systems of Equations
by Kathleen DuhlThis lesson focuses on solving systems of linear equations using linear combinations (elimination) method.
