Systems of Equations and Inequalities
In order to receive a C for this Unit you must complete the first four items and then select
at least one item in each of the following categories.
_____ Watch the videos that are posted in the Chapter 3 folder on the class webpage and take
notes on each video. (6 points)
_____ Answer the four questions posted on the blog for our class and respond to at least one
other student on each blog questions. (8 points)
_____ Earn a badge on the khan academy website for solving systems of equations by
substitution. (10 points)
_____ Earn a badge on the khan academy website for solving systems of equations by
elimination. (10 points)
_____ Vocabulary: system of equations, consistent, inconsistent, independent, dependent,
substitution method, elimination method, system of inequalities. (8 points)
1. Create a set of flash cards that define each of the vocabulary terms for this unit. The
front of the card should have the term; the back should include an illustration of the term
and a definition written in your own words.
2. Write a vocabulary test for the terms that are used in this unit. Include illustrations and
an answer key.
3. Create a display for the classroom that defines each of the given terms in your own
words.
_____ solving systems of equations by graphing (10 points)
1. Work with a partner to write three original systems of equations, one that is consistent
and independent, one that is consistent and dependent, and another that is consistent.
(Both partners need to turn in the work to receive credit). Graph your systems, provide
the solution, and label them accordingly.
2. Complete the self-check quiz for 3-1 and e-mail your results to libebr@whsd.net
3. Page 113 13-18, 25-28
_____ solving systems of equations using substitution (6 points)
1. Page 120 13-18
2. Write a letter to a student in another school explaining how to solve a system of equations
using substitution. Use at least two example problems in order to walk them through the
process.

Complete the “People Search” page
Use your calculator to solve the 25-27 on page 120, then solve each problem using
substitution AND elimination
In order to receive a B for this unit you must complete at least 2 of the following activities
worth 5 points each.
_____ Practicing all three methods by playing the systems card game in a group of 3 people.
Turn in your work for the entire activity.
_____ See me in order to select 4 word problems at random and solve each problem using the
method of your choice.
_____ Work with a partner to create a collection of 6 original word problems (sports usually
work well) that can be solved using systems of equations. The original problem should
be on the front of each page and the solution should be on the back of each page.
In order to receive an A for this unit you must complete AT LEAST one of the following
activities. (10 points each)
_____ Create a 10 minute video summarizing the different methods for solving a system of
equations and using examples. Discuss the reasons why you would solve using each
different method. (You may work in a group of up to three people)
_____ Look at the 6 system of equations word problems on page 149 (4-9). Solve each problem
using any method you choose. For each problem, explain the method that you chose,
how you decided on the method, and the steps involved in solving the system.
_____ Write a poem or short story about the different relationships between lines in systems of
equations (consistent and independent, consistent and dependent, or inconsistent)
You will earn 2 additional points if this is turned in at the beginning of class on Friday,
October 7 along with this page.
