Amy verified owner — January 28, This Common Core Algebra 2 has been a lifesaver. The enormity of the CC Alg 2 curriculum makes it hard to know how to pace and from the beginning this has been my guide. I do combine some shorter lessons and units in order to have time for review, but editable versions of all documents make that an easy task.

The subscription includes all the notes, homeworks, quizzes, review and tests for all units. I highly recommend it for any Algebra 2 classroom. The book aligns with the NYS standards, my regents results are extremely high. Material is an awesome base to work from, especially the sequence and pacing. The kids love having the videos to reference if they miss time or need a little extra review.

The scaffolding of the HW I think is pretty great, starting with basics and moving up to regents level questions and other extensions. Overall a really quality product and a great value!

The answer keys come on the Version 2. Please see our Products page for full details. We are currently working on Algebra 1 Lessons 1 through So glad to have found the reviews as well. Are there quizzes or tests to accompany each lesson, along with answer keys?Students continue their study of quadratic equations, learning new strategies to determine the vertex and roots of quadratic equations and applying these in various real-world contexts.

In Unit 8, Quadratic Equations and Applications, students continue their study of quadratic equations from Unit 7. They learn the three common forms of a quadratic equation—standard form, intercept form, and vertex form—and understand how to use these forms efficiently based on the situation at hand. Students also learn new strategies to determine the vertex and the roots of a quadratic equation and then apply these strategies in various real-world contexts. In Topic A, students are introduced to the vertex form of a quadratic equation.

They use their factoring skills from Unit 7 to determine the process of completing the square. Using the process of completing the square, students are able to derive the famous quadratic formula, enabling them to solve for the roots of any quadratic equation. Students investigate examples of quadratic equations with two, one, and no real roots, and make the connection of the number of real roots to the value of the discriminant.

Throughout the lessons in this topic, students pay attention to the structure of the equations to determine which strategy and approach are the most efficient way to solve. Students then write and analyze quadratic functions to represent different real-world applications involving projectile motion, profit and revenue models, and geometric area applications.

Lastly, students investigate systems of equations where one of the equations is a quadratic equation. This assessment accompanies Unit 8 and should be given on the suggested assessment day or after completing the unit. The central mathematical concepts that students will come to understand in this unit. Quadratic functions can be used to model a variety of real-world contexts such as projectiles and falling bodies, profit and revenue models, and geometric areas.

The key features of quadratic functions, interpreted in context, provide information on values such as break-even points, revenue-maximizing selling prices, peak heights, and maximum measurements.

The materials, representations, and tools teachers and students will need for this unit. Internalization of Standards via the Unit Assessment. Describe features of the vertex form of a quadratic function and write quadratic equations in vertex form from graphs.

## Unit 8 – Quadratic Functions and Their Algebra

Complete the square to identify the vertex and solve for the roots of a quadratic function. Solve and interpret quadratic applications using the vertex form of the equation.

Solve quadratic equations by inspection e. Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. Modeling is best interpreted not as a collection of isolated topics but in relation to other standards. The star symbol sometimes appears on the heading for a group of standards; in that case, it should be understood to apply to all standards in that group. Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.In earlier grades, students define, evaluate, and compare functions and use them to model relationships between quantities.

In this module, students extend their study of functions to include function notation and the concepts of domain and range. They explore many examples of functions and their graphs, focusing on the contrast between linear and exponential functions. They interpret functions given graphically, numerically, symbolically, and verbally; translate between representations; and understand the limitations of various representations.
