Project Menu for Algebra 2 Honors (can be adapted to Trigonometry/Math Analysis)
You will complete and present 2 projects each semester. You must do one by the end of
the quarter, but can do both projects first quarter. You will be given a chance to revise
your project based on feedback (if it is turned in early enough).
Bonus 1: If you know of an application I haven’t listed, you can propose your own
project for any chapter. (I’ve included some suggestions from last year)
Bonus 2: If homework is a waste of your time, you can complete one of the projects for
each chapter instead of doing homework for the chapter. The points given for the project
will equal the total number of homework points for the chapter.
Good projects require:
Processing Skills (making sense of new content)
Content (facts, concepts, skills, principles and attitudes)
Resources (use of appropriate research skills)
Product (a well designed product)
Citation of sources (include any websites, books, interview subject information, etc.)
Chapter 2: Functions in the real world:
Graphs can be used to represent “real world” situations where one variable is related to
another.
 Correct scale and labeling of axes is important.
 Graphs may have limited ranges of validity.
 Graphs can be used to misrepresent data.
1. Pick several of the “word problems” from section 2.3 and draw the graphs that go
along with them (labeling the axes properly in units that can be measured). Make up
several more of your own. What are the domain and range for each graph? Can the

domain and range be extended in the positive direction? The negative direction?
Why or why not? Illustrate your graphs for a lovely poster presentation.
Given a set of graphs, make “real world” problems that are represented by the graphs.
Label the axes correctly in units that can be measured. What are the domain and
range for each graph? Can the domain and range be extended in the positive
direction? The negative direction? Why or why not? Illustrate your graphs for a
lovely poster presentation. Cite your sources, if any.
Pick a “real world” example from another class (social studies, PE, science) where
one aspect varies with another aspect with a constant of variation. Cite your sources.
Show several examples (graphically) with different constants of variation. Compare
and contrast the graphs. What are the domain and range for each graph? Can the
domain and range be extended in the positive direction? The negative direction?
Why or why not? Illustrate your graphs for a lovely poster presentation.
Lies, damn lies and statistics I. Find several graphs from the newspaper, your text
books and/or magazines that are in some way unclear (I’ve found USA Today has
graphs that misrepresent data). Evaluate the graphs, write your evaluation of the
graphs in paragraph form. (Are the scales correct? Does the graph represent what it
claims?) If you were to improve the graph, what improvements would you make?
Can you continue the x-axis scale to go beyond the scale in the graph? Present your
graphs and “arguments” in poster form. Cite your sources.
Lies, damn lies and statistics II. Graphs can be used in the media or in reports that
have correct scale and are correctly labeled but that can be used to misrepresent the
data. Pick some data from an area that interests you and represent the data in three
different graphs that make the results “look” very different. Under what circumstance
would you use each of the graphs to persuade an audience? Cite your sources.
Present your graphs and “arguments” in poster form.
Chapter 3: Linear functions
Graphs can be used to represent “real world” situations where one variable is related to
another by a linear equation.

zero slope? an undefined slope?)
 Slope and y-intercept have “real world” meaning.
 Positive, negative and zero slopes have “real world” meaning.
 Different positive slopes have “real world” meaning.
 The domain and range of the problem may have limited validity.
 When we use linear models we may be ignoring some “real life” effects.

form. Describe your interviewee and their job. Describe how they use linear
equations. Include at least one example of a linear equation they use. Graph the

Chapter 4: Systems of Equations
Systems of equations and linear inequalities can be used to describe real world
situations.
 The point(s) of intersection are the solution(s) to both equations.
 Some systems have no solutions.
 Some systems have infinitely many solutions.
 There are many ways to solve systems of linear equations.
 “No solution” and “ infinitely many solutions” appear differently in the different
methods.
 Systems of 3 equations in 3 unknowns can be solved in similar methods.

should be able to show graphing a point in 3-dimensions. You should also be
able to graph planes in 3-space. Be able to show the examples described in
problem 5 on page 138.
2) Research the 4th dimension. If a point on a line shows zero space in 1
dimension and a line in a plane shows 1 dimension in 2 dimensions and a
plane in 3 dimensions shows 2 dimensions in 3 dimensions, how would you
extend the 3 dimension coordinate system into the 4th dimension. Present
your research results in either poster or report form. Include drawings/models
to illustrate what you’ve learned. Cite resources.
3) Systems of equations are defined as “inconsistent”, “dependent” or
“independent”. Look up these words in the dictionary. (cite your sources)
What are the definitions of these words when you are not talking about
systems of equations (the non-mathematical definition(s)). What are the
definitions of these words when you are talking about systems of equations
(the mathematical definition). How can you connect the mathematical and
non-mathematical definitions of these words? Illustrate your examples with
graphs of systems. Present your results in paper or poster form.
4) Write a program for the graphing calculator that will solve a system of two
linear equations in two variables. See problem 20, page 125 for the details of
this project. You will demonstrate your program for me and explain to me the

vertex.
 Zeros/roots/solutions of quadratic functions represent the x-intercepts of the
graph.

Everyone will do a project for chapter 5. These are additional projects are for
students who want to do a project instead of doing homework for the chapter.
1) Find an example of the graph of a quadratic function in a work of art or
architecture. Draw a coordinate graph system over the picture of the work of art
or architecture that you’ve chosen (you may need to enlarge the quadratic part of
the artwork to draw a set of coordinate axes. If so, please include a copy of the
original work of art or architecture as well). Mark the scale clearly. Find the
coordinates of three points on your graph and use these three points to find the
equation of your quadratic function. Show the work for finding your equation.

model works for that point by substituting into your equation. Show this work
too. Present your results in a well written report or neat, well organized poster.

article. Present your results in paper or poster form.
Chapter 6: Exponential and Logarithmic Functions
Exponential and logarithmic equations can be used to model “real world” situations.

of negative “a”? of “b” > 1? of “b” < 1?).
 Properties of exponents are derived from repeated multiplication.
 Exponentiation properties extend to negative, zero, reciprocal and fractional
exponents.

an example using all of the students at the school where each person is asked to
send the letter (or money or good luck) to four or five other people. How long
would it take to include all of the students in the school? All of the people in

phenomena in a particular location which appear as sine waves include average
times of moonrise or moonset, high or low temperatures, hours of daylight or
