Algebra 2

 

This page is an archive from when I last taught Algebra 2, with most files relating to Honors Algebra 2 from the 2008-2009 school year.

While I will certainly update things if I ever teach an Algebra 2 course again, I thought a few things here might be useful to others now.

Calendar
Textbook

Back to Main

The Syllabus offers a brief overview of course, including grading and classroom policies, for the Honors Algebra 2 course.  The current version is for the 2008-2009 school year and is the same one shared among all Honors Algebra 2 teachers at RHS.

 

The Calendar is my "semester plan" that I use as a pacing guideline for the current course I'm teaching.  While it will inevitably change as the semester goes on (and I try to update it here from time to time), it might be a useful reference for the students as well.  UPDATE:  The new one for the spring, 2009, semester is now posted.

 

SharePoint is the Williamson County Schools site used by its educators, and this link is the directory for the Ravenwood faculty.  It contains resources and a homework calendar for each teacher and class.  Much of the information there is also contained here, but some might prefer the setup in SharePoint.  I will be posting daily assignments on the SharePoint calendar.

 

The Textbook link is a website created specifically for our textbook by the publisher Glencoe / McGraw Hill.  There are extra practice problems, self-check quizzes, and practice chapter tests... all of which can be useful in class.

 

Advanced Grapher is a graphing software application that allows students to graph relations of different types in one window, including scatter plots .  Students can click the Advanced Grapher link to download the software for use at home in the event they do not have access to a graphing calculator at home.  A product key is required after 30 days, but I'm working on getting a site license for the students.

 

 

Classroom Supplements and Enrichments.

 

By now you have probably noticed that I don't follow the book exactly.  I like to add, subtract, and rearrange chapters to better fit our needs.  The resources below are intended to supplement and/or enrich what is in our current textbook.

 

bullet

Linear Modeling Activity - Here is a copy of the assignment involving linear modeling.  If you are interested in the worksheet we did in class together (it might help you with the graded activity), you can find it here.

 

bullet

Common Parent Functions - There are several "new" parent functions that are used in Algebra 2.  This document highlights the more common ones, including some of their properties.

 

bullet

Function Transformations - Here is a summary of the work we explored in class, including a little additional terminology.  For additional help, check out the site from Hofstra University that provides information and practice on function transformations. If you would like to try something a little more basic to start with, PurpleMath has this tutorial.

 

bullet

Systems of Equations in Three Variables - These are the notes from the lesson on solving systems of linear equations in three variables.  It includes three examples - one each for a single solution, no solution, and the solution to a dependent system.  The homework worksheet is also included here.

 

bullet

Linear Programming Example - Here is a "portfolio quality" solution to one of the linear programming examples from our textbook.

 
bullet

Elementary Row Operations - This is an introductory mini-lesson and worksheet on the three elementary row operations for matrices.

 
bullet

Finding Inverse Matrices - For those interested in techniques for finding the inverse of any square matrix, this is the document for you.

 
bullet

Finding Determinants - This document not only reviews the techniques for evaluating 2x2 and 3x3 determinants, it also outlines the expansion by minors technique that can be used for any determinant.

 
bullet

Area of a Triangle - This document defines, proves, and gives some examples of using determinants to find the area of a triangle given three vertices.

 
bullet

Polynomial Summary - Here is a summary of the more important concepts involving polynomial functions, including a couple of examples.

 
bullet

Solving Polynomial Equations - This is a brief review of a strategy for solving polynomial equations.  This does assume that the reader understands the Rational Root Theorem and synthetic division.

 
bullet

Extreme Values - This is a brief exploration on using calculus concepts to locate the exact values for relative maximum and minimum values on the graph of a polynomial function.  Don't worry... no calculus experience required!

 
bullet

Conics Introduction - This is a brief introduction to the four main conic sections.  It highlights the names, equations, and graphs of the circle, ellipse, hyperbola, and parabola.

 

 

Resources for Help and Review.

 

As the needs arise, I'll try to add resources here that might offer a little additional support.

 

bullet

Calculator Basics - Unfortunately, not all Algebra 1 students have the opportunity to use graphing calculators in their studies... but you will certainly need them in Algebra 2!  This document is a first timer's step-by-step guide for a few of the functionalities that we use in class (it's also handy for anyone who has forgotten the steps).  In particular, this document illustrates how to enter lists of data, create a scatter plot, and find the line of best fit.

 
bullet

Excel Basics - Some of the activities in class require the use of Excel for graphing and/or finding model equations.  This document walks those unfamiliar with the software through a linear example.

 
bullet

Graphing Systems of Inequalities - This is a tutorial document on how to graph systems of inequalities using the program Advanced Grapher.  If you would like to see the AG file used in the screen shots, you can download it here.

 

bullet

Graphing Linear Equations - This is a brief review of a strategy for graphing linear equations.

 
bullet

Writing Linear Equations - Here is a graphic organizer to help with writing linear equations.

 
bullet

Solving Linear Equations - This document outlines a strategy for solving practically any linear equation in one variable.  It includes several examples along with a few tips at the end.

 
bullet

Systems of Equations in Two Variables - Here is a review on solving systems of linear equations from Algebra 1.  It includes one example of each type of system solved three different ways.

 
bullet

Factoring Review - This document offers a strategy for factoring basic polynomials using the major techniques from Algebra 1.

 
bullet

Solving Inequalities - This is a link to a site that finds solutions to polynomial and rational inequalities.  I thought others might enjoy it.

 
bullet

Exponential Growth and Decay - Here is a little presentation lesson I have used in Algebra 1.  It pretty much describes the growth and decay models as well as give some examples.

 
bullet

Sequences and Notation - I realize that I teach and use sequences differently than our textbook, so I've put together this brief introduction on the notation and terminology for those that might want it for reference.

 
bullet

Unit Circle - Here is a link to the completed unit circle illustration from the trigonometry class (I thought it might be useful here).

 

 

Activities and Projects.

 

Here are the major activities that we will do in class as time permits.

 

Teachers:  Most of these are adaptations from the activities and labs on my Algebra 1 and AP Calculus pages, so you might check those out to see if they are more appropriate for your needs.  Some of these activities need a little updating with screen shots and calculator keystrokes, but you can at least use them as a starting point (feel free to edit as you see fit).

 

bullet

Flight Lab (linear modeling) - In this activity, students must research flight times from the Internet and then model and analyze the data.

 
bullet

Falling Object Activity (quadratic modeling) - This activity has students take data from a free falling object experiment and then analyze the motion's position and velocity behavior.

 
bullet

Complex Operations Assignment (complex numbers) - Here is the assignment and rubric that involves the algebraic and geometric interpretations for certain operations of complex numbers.

 

bullet

M&M Lab (exponential decay) - This activity has students perform an experiment with candy to simulate radioactive decay.

 

bullet

Population Lab (exponential growth) - This activity has students research and analyze location population data.

 

bullet

Direct Variation Lab (direct variation) - This activity has students measure several objects to model a direct variation.

 

bullet

Boyle's Law Lab (inverse variation) - This activity has students use a gas pressure sensor in an experiment to model the relationship between volume and pressure.

 

 

Assessment Solutions and Review.

 

UPDATE:  This is where I had been posting solutions to quizzes, tests, and the occasional activity, but I'm afraid I can no longer post quiz solutions.  Apparently there was a student/parent concern on how make-up quizzes were being handled and the resulting administrative action makes it impractical to continue posting those solutions.  I apologize to those that have been using these quizzes in preparation for the chapter tests.

 

I plan on still posting test solutions once all make-ups are in, so hopefully students can use those to prepare for major exams.  From time to time, I will temporarily post solutions to worksheets or activities as the need arises.

 

Pre-Assessment Test 4 Test 7-8 Test 12*
Test 1* Test 5 Test 7-9  
Test 2 Test 6 Test 10  
Test 3 Test 9 Test 11  

 

* The test over Chapter 1 was used by other teachers who preferred not to post the questions in the event it might be used again.  I'll use different versions from now on so students can still get the solutions.  The one over Chapter 12 still had make-ups to be completed by finals time, so I couldn't post it.

 

Interested in a little extra review for the "big" tests?  I'll post the review topics below as they become available:

 
bullet

1st Quarter Exam - The topics here cover Chapters 1-4, plus a few additional concepts.

 
bullet

1st Semester Exam - This is the review packet put together for the fall semester exam.  The topics cover Chapters 1-6, 9, plus a few additional concepts.

 
bullet

3rd Quarter Exam - The topics here cover most of Chapters 7-10, plus a few additional concepts.

 
bullet

2nd Semester Exam - This is the system-wide set of review problems for the CCA (common county assessment).  The problems include topics from both semesters.  The review contains the answers to each problem on the last page, but I (quickly) put together sample solutions for those that might like a little more help.

 

 

Additional Resources. 

 

Here are a few additional links that students can use for finding extra help (study guides, practice worksheets, etc).  I haven't used them much myself, but other students have and seem to find them useful.

 

bullet

Algebrahelp.com - This site contains lessons, worksheets, and calculators listed by topic.  The calculators will work out problems step-by-step so that students can get an idea of not only the answer, but the solution to that answer.

 

bullet

Purplemath - This site acts as a portal to other help sites, but there is a lesson index at the right that offers help by topic (most of the topics in Algebra 1 can be found under Beginning Algebra Topics and Intermediate Algebra Topics).

 

bullet

Algebra.com - This site advertises free help with algebra homework and has tutorials and problem solving calculators.

 

bullet

SparkNotes - This site offers more than just math help and can be a little overwhelming with everything it offers, so this just links you directly to the math help index.
