Westside High School Lesson Plan
Teacher Name:
Garrett, Shannen
Unit Name and #:
Unit 3:
Equations and
Inequalities
Course:
Algebra II B MOD
Dates:
Feb 16 – Feb 20, 2015
What are we learning?
Daily Objective:
 Students will test values to determine the solution sets of linear inequalities in one
variable.
 Students will use algebra to solve linear inequalities in one variable
 Students will graph the solution sets of linear inequalities in one variable on a number
line.
Students will discover that multiplying or dividing an inequality by a negative number causes
the direction of the inequality sign to reverse.TEKS/AP/Standards:
Ⓢ ALGI.7A Analyze situations involving linear functions in forms of a graph, table, equation, or
verbal description in order to formulate a linear equation or inequality to solve problems.
Ⓡ ALGI.7B Investigate methods for solving linear equations and inequalities using concrete
models, graphs, and the properties of equality, select a method, and solve the equations and
inequalities involving one variable or two variables.
Ⓢ ALGI.7C Interpret and determine the reasonableness of solutions to linear equations and
inequalities.

TEKS/AP/Standards:
Ⓡ ALGII.6A Determine the reasonable domain and range values of a quadratic function
represented by a table of values, graph, function rule, or a contextual situation, as well as
interpret and determine the reasonableness of solutions to quadratic equations and inequalities.
Ⓡ ALGII.6B Relate representations of quadratic functions in algebraic, tabular, graphical, and verbal
forms.
Ⓡ ALGII.7A Use characteristics of the quadratic parent function to sketch the related graphs and
connect between the f(x) = ax2 + bx + c and the f(x) = a (x – h)2 + k symbolic representations of
quadratic functions, and write the quadratic function in
f(x) = ax2 + bx + c or f(x) = a (x – h)2 + k given the graph of the function.
Ⓢ ALGII.7B Use the parent function to investigate, describe, and predict the effects of changes in a, h,
and k on the graphs of y = a(x – h)2 + k form of a function and what those changes in symbolic
representation may mean in a real world applications
