Product Description
I created this PowerPoint lesson for my Algebra 1 classes. It corresponds to Section 2.5 in the Prentice Hall textbook -- California Algebra 1. This lesson shows students how to solve a variety of word problems: Perimeter Problems, Consecutive Integers (with consecutive evens and consecutive odds included), and Distance Problems (using rate x time = distance). Because class time does not allow for students to copy the problems down, and work them out, (and just having the algebra doesn't help them with their homework), I created a Word document that I xerox for them to use as notes. This is also included.

4.0 Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x-5) + 4(x-2) = 12.
5.0 Students solve multi-step problems, including word problems, involving linear equations and linear inequalities in one variable and provide justification for each step.

Common Core Standard:
A.EE.7 Solve linear equations in one variable.
a. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).
b. Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

Note: Math Type 3.0 and/or Math Type 5.0 were used to create this lesson.
