Product Description
A lesson on Pythagorean Theorem!

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 determine the length of a missing side of a right triangle, determine if given sides measures would determine a right triangle, and find the distance between two points on the coordinate plane.

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 would benefit from a working understanding of the Pythagorean Theorem. Students should be able to evaluate roots, approximate irrational roots, solve two step equations, and plot points in the coordinate plane.

STANDARDS DRIVEN: This is a lesson designed for students who have already had experience using the Pythagorean Theorem. Students will be primarily expected to determine if three side length would determine a right triangle, find the missing side of a right triangle, approximate irrational lengths of right triangles, and use their understanding of right triangles to calculate the distance between points on the coordinate plane. Students will be expected to extend this to developing the distance formula and understand how it relates to the Pythagorean Theorem. This lesson follows a lesson on classifying numbers into number sets and precedes a lesson on solving multi-step linear equations with no/infinite solutions.

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.
