OBJECTIVE: All students will be able to classify numbers as rational, irrational, integers, and/or whole numbers.


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 determine if a radical is rational or irrational, evaluate expressions with exponents, have worked with perfect squares, have a knowledge of inverse operations, add/subtract/multiply/divide rational numbers, and determine absolute values.

STANDARDS DRIVEN: Students are primarily expected to determine if a number is rational or irrational and classify rational numbers as rational, integers and/or wholes. Students will be expected to extend this determine truth values of statements and provide counterexamples to disprove statements. This lesson follows a lesson on approximating irrational numbers and precedes a lesson on the Pythagorean Theorem.

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.
