A lesson on LINEAR FUNCTIONS – COMPARING SLOPE 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.

OBJECTIVE: All students will be able to compare the slope of linear functions / equations represented multiple ways. (functions, tables, graphs, word problems)

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 graph linear functions, write linear functions from graphs, write linear functions given two points, write linear functions from tables, write linear equations in y=mx+b form, identify slope and y-intercept from a function, identify slope and y-intercept from graphs, and compare rational numbers.

STANDARDS DRIVEN: Students are primarily expected to understand that linear functions can be expressed several ways and that their attributes can be compared. This lesson will follow a lesson on expressing functions in y=mx+b form and will precede a lesson on comparing functions within context.

MATERIALS NOTES:
This is an editable word file that includes 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.
