Cluster: Solve equations and inequalities in one variable

Standard: Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.

## CCSS.Math.Content.HSA-REI.B.4b: Strong (2)

The resources in this curriculum guide cover a variety of math content, some of which are in this standard. However, some of the content for this standard is not sufficiently addressed to render it a superior rating.

## Opportunities for Deeper Learning: Strong (2)

Several of the resources in this guide contain two or more deeper learning skills. The main reason for rating it as a 2 is that some of the materials still could use some stronger directions and appropriate scaffolding for adult education students and teachers.

## Quality of Instructional and Practice Exercises: Superior (3)

There are several resources in this guide that invite students to explore and examine real-world scenarios before solving the math. The traditional procedural work also can be found in the "Elementary Algebra" book.

## Quality of Technological Interactivity: Superior (3)

The "Quadratic Function Explorer" is a wonderful interactive resource for students to explore what happens when the values for the three coefficients are adjusted. It's very easy to use simply by trial and error to get students noticing and wondering, and the "Things to Try" below the interactive offer some additional ideas for students to try out with the simulator.

## Quality of Assessments: Not Applicable (N/A)

There were no specific assessments used in this guide; however, some informal "readiness quizzes" are available in the "Elementary Algebra" book provided.

## Utility of Materials Designed to Support Teaching: Limited (1)

More guidance or instruction on how to use the various OER in this guide is needed for a teacher to best utilize the materials in the suggested format. For example, the "Elementary Algebra" book introduced as a resource for a flipped classroom suggests reviewing chapter 2 as a means of introducing students to what will be covered in the class. Chapter 2 focuses on linear equations and inequalities, yet the core standard addressed is quadratic. Quadratics are discussed in chapter 10.

## Quality of Explanation of the Subject Matter: Limited (1)

There are wonderful resources in this guide; however, more detail about how to use them is needed. For example, the "Art of Problem Solving" has 13 chapters of videos. Some guidance and specific placement of when to use what chapters in the instruction would be helpful and make this resource less daunting to students and teachers.

This resource provides an excellent continuum of learning activities focused on building an understanding of quadratic equations, by providing good explanations for instructors,. Suggestion to instructors - any gaps can easily be filled with a quick online search for specific elements of the topic. The final suggested exercise of Paper rockets is exceptional for real-world application.
