6.0 Quick Draws
PDF
|
This
form can be used as a warm-up or quiz to help students develop
fluency in the attributes of different equations
|
Alg
6.1 Parallel and Perpendicular PDF
*Graph
*PDF |
Students
figure out equations and graphs for lines which are parallel
and perpendicular. *Access the graph at left. |
Alg
6.2 Detective Work in Linear Equation Forms
PDF
|
Students
use what they know (points, slopes, x and y intercepts, equation
forms etc.) to find out what they don’t know (points,
slopes, x and y intercepts, equation forms etc.). |
Alg
6.3 Art and Linear Equations PDF
|
This
activity uses calculator art to assess student knowledge of
linear equations. |
Alg
6.4 Chickens and Pigs, Introduction to Systems
PDF
|
Students
use trial and error to figure the solution to the chickens
and pigs problem. In the process, they deal with the ideas
for writing two equations. From this experience, they create
a table and a graph, write two equations into the calculator
or computer. They explain the equations and graphs. |
Alg
6.5 Systems of Equations and Their Graphs
PDF
|
Students
solve systems of equations problems “Where does the
money go,” and “Renting Skates” using graphs.
They revisit the Chickens and Pigs problems to study the substitution
and elimination strategies for solving systems of equations.
They practice solving problems using these methods. |
Alg
6.6 Graphing Inequalities
PDF
|
Four
students in a group each analyze an inequality statement.
They substitute points (from all four quadrants with x and
y values from -3 to +3) into the inequality to evaluate
greater than, less than, or equal. After the analysis, students
compare results, and examine the patterns in the table they
have created. Then they shade in graphs based on the patterns
they observed in the four inequalities.

Alg
6.7 Systems of Inequalities and Absolute Value
PDF
|
In
this lesson, students examine different forms of inequality
statements, simple and compound inequalities, a two variable
inequality, an inequality involving absolute value and systems
of inequalities. They examine the equations and the graphs
and then practice different examples. |
