Strand: ALGEBRA  Seeing Structure in Expression (A.SSE)
Interpret the structure of expressions
(Standards A.SSE.1–2). Write expressions in equivalent forms to solve problems, balancing conceptual understanding and procedural fluency in work with equivalent expressions
(Standard A.SSE.3).
Standard A.SSE.3
Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression. 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.^{★}

The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for the Secondary Mathematics II  Seeing Structure in Expression (A.SSE)

Algebra Team: Overview of Teaching Styles
This Teaching Channel video illustrates how two teachers' collaboration impacted their algebra program. This site provides a lesson plan and student handouts. (10 min.)

Comparing Investments
This lesson unit is intended to help you assess how well students are able to interpret exponential and linear functions.

Forms of exponential expressions
There are many different ways to write exponential expressions that describe the same quantity, in this task the amount of a radioactive substance after t years. Depending on what aspect of the context we need to investigate, one expression of the quantity may be more useful than another. This task contrasts the usefulness of four equivalent expressions. Students first have to confirm that the given expressions for the radioactive substance are equivalent. Then they have to explain the significance of each expression in the context of the situation.

Horseshoes in Flight (pdf)
Students analyze the structure of algebraic expressions and a graph to determine what information each expression readily contributes about the flight of a horseshoe. This task is particularly relevant to students who are studying (or have studied) various quadratic expressions (or functions). The task also illustrates a step in the mathematical modeling process that involves interpreting mathematical results in a realworld context.

Ice Cream
This task illustrates the process of rearranging the terms of an expression to reveal different aspects about the quantity it represents, precisely the language being used in standard ASSE.B.3. Students are provided with an expression giving the temperature of a container at a time t, and have to use simple inequalities (e.g., that 2t>0 for all t) to reduce the complexity of an expression to a form where bounds on the temperature of a container of ice cream are made apparent.

Identifying Quadratic Functions (Standard Form)
This task has students explore the relationship between the three parameters a, b, and c in the equation f(x)=ax2+bx+c and the resulting graph. There are many possible approaches to solving each part of this problem, especially the first part.

Introduction to the Materials (Math 2)
Introduction to the Materials in the Mathematics Two of the The MVP classroom experience begins by confronting students with an engaging task and then invites them to grapple with solving it. As students ideas emerge, take form, and are shared, the teacher orchestrates the student discussions and explorations towards a focused mathematical goal. As conjectures are made and explored, they evolve into mathematical concepts that the community of learners begins to embrace as effective strategies for analyzing and solving problems.

Module 2: Structures of Expressions  Student Edition (Math 2)
The Mathematics Vision Project, Secondary Math Two Module 2, Structures of Expressions is both a functions module and an algebra module. It is designed to extend students knowledge of quadratic functions and to reinforce two big ideas of functions, Functions can be transformed in the same, predictable way and Different algebraic forms have purpose in different situations.

Module 3: Solving Quadratics & Other Equations  Student Edition (Math 2)
The Mathematics Vision Project, Secondary Math Two Module 3, Solving Quadratics & Other Equations. The idea that different quadratic forms are useful in graphing is extended in Module 3, Solving Quadratic and Other Equations, when students use different forms of quadratic equations to find the roots or solve quadratic equations of a single variable.

Nonlinear Functions video
This video introduces nonlinear functions.

Profit of a company
This task compares the usefulness of different forms of a quadratic expression. Students have to choose which form most easily provides information about the maximum value, the zeros and the vertical intercept of a quadratic expression in the context of a real world situation. Rather than just manipulating one form into the other, students can make sense out of the structure of the expressions.

Representing Conditional Probabilities 2
This lesson unit is intended to help educators assess how well students understand conditional probability.

Representing Quadratic Functions Graphically
This lesson unit is intended to help educators assess how well students are able to understand what the different algebraic forms of a quadratic function reveal about the properties of its graphical representation.

Rewriting a Quadratic Expression
The goal of this task is to complete the square in a quadratic expression in order to find its minimum or maximum value.

Solve Quadratic Expressions by Factoring video
This video introduces and explains the concept.

Sorting Equations and Identities
This lesson unit is intended to help educators assess how well students are able to recognize the differences between equations and identities, as well as substitute numbers into algebraic statements in order to test their validity in special cases.

Taxes and Sales
This task is not about computing the final price of the shirt but about using the structure in the computation to make a general argument.

Vertex of a parabola with complex roots
The goal of this Illustrative Mathematics task is to study the relationship between the roots of a quadratic function and its graph.
