Product Description
A lesson on Solving Multi-Step Linear Equations in One Variable with Extraneous Solutions brought to you by Tom Foolery!

This lesson was created for students preparing for the 9th grade NYS Common Core Regents Exam in Algebra. This lesson instructs and assesses students on multiple Common Core State Standards.

WHAT YOU GET:

WORD document (20 pages)
includes the lesson elements below & partial key

OBJECTIVE: All students will be able to solve multi-step linear equations in one variable which result in infinite or no solutions. Students will also be able to determine the number of solutions by simple inspection.

LESSON ELEMENTS:

DO NOW: spiraled review designed to build momentum in the opening moments of class
MAD MINUTE: timed practice on essential basic skills – designed to build automaticity
WARM UP: longer review on prior lesson – designed to build fluency toward mastery
PRACTICE: quick hits and more challenging at-bats – assess ability with increased rigor
EXPLORE: allows students to access guided discovery of new concept before delivery
RULES & TOOLS: instructional delivery of new concept – rules, steps and procedures
GUIDED PRACTICE: gradual release of cognitive work with increasing rigor
INDIVIDUAL PRACTICE: multiple problems with increasing rigor and varied problem types
BREAK DOWN & LIGHT UP: student analysis of concept – written reflections and extensions
REVIEW: spiraled (often recycled) review on the more rigorous aspects of prior standards
EXIT SLIP: informal assessment of student progress toward mastery of objective
HOMEWORK: front & back assignment that includes work from current and prior standards
KEY INCLUDED – embedded in word document (as comments) (hidden when printed)

LESSON NOTES:

PRIOR KNOWLEDGE: Students should know how to solve multi-step linear equations in one variable, add / subtract / multiply integers, add / subtract / multiply / divide signed rational numbers, use the distributive property, simplify expressions by combining like terms, identify properties of equality and justify their use, substitute to verify solutions, and identify solutions as valid or invalid.

STANDARDS DRIVEN: Students are primarily expected to solve multi-step linear equations in one variable resulting in infinite, no or one solution. Students will be expected to extend this ability to determine the number of solutions given a linear equation in one variable. This lesson follows a lesson on solving multi-step linear equations in one variable and will precede a lesson on solving simple quadratic equations.

MATERIALS NOTES:
This is an editable word file that includes a partial key as margin notes / comments (these can be hidden in the “Review” Pane) I create my documents in compatibility mode because it allows users more control over pictures and graphs. To ensure that you are getting the best quality, you should not save the file in any new format as certain design elements may be lost.
