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.
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)
PRIOR KNOWLEDGE: Students should know how to solve multi-step linear equations in one variable, evaluate expressions with square roots, evaluate absolute value expressions, verify solutions using substitution, and using square roots to isolate a base.
STANDARDS DRIVEN: Students are primarily expected to solve absolute value equations, simple quadratic equations and verify solution sets.. This lesson follows a lesson on solving multi-step linear equations with extraneous solutions and will precede a lesson on solving two-step linear inequalities in one variable.
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.
