Pythagorean Theorem & Irrational Numbers Math 8 - Mrs. Davis

Essential Questions: ● What are square roots? What are cube roots? ● How do I classify numbers as rational and irrational? ● How do I write approximations of irrational numbers and use these to compare numbers? ● What is the Pythagorean theorem and how can it help find distances along a diagonal?

Grading and Assessments End of Unit Assessment (70% of grade): This unit will be divided into 2 assessments. Both assessments will be combined to make ONE final unit score. ● Squares, cubes & irrational numbers - September 17/18 ● End of Unit Assessment - October 1/2

Grading and Assessments Focus Areas (SDL) (21% of gr ade): ● Pythagorean Theorem & Irrational Numbers ○ ○ Objective 1: Solve equations and evaluate expressions involving perfect squares, perfect cubes, square roots, and cube roots. Objective 2: Apply the Pythagorean Theorem to solve problems on and off the coordinate grid. Additional Focus Areas (SDL) (9% of grade): ● More on Pythagorean Theorem & Irrational Numbers ○ ○ ○ Objective 1: Distinguish between numbers that are rational and irrational. Objective 2: Work fluently between fractions and their decimal expansions. Objective 3: Estimate the values and number line locations of irrational numbers.

Grading and Assessments Credit for Class: Learners must earn at least a 70% average for End of Unit Math Assessments AND pass ALL their Power Focus Areas.

Self-Directed Learning (SDL) Important Reminder: Learners should be taking Diagnostic Tests and working on their resources for Power Focus Areas at HOME. This will allow them time IN CLASS on SDL Day to take Content Assessments. SDL Day is either on Thursday or Friday in math depending on whether the learner has math during an odd or even class period.

Dates to Remember: UNIT 1: Pythagorean Theorem and Irrational Numbers Start Date: September 3 Mid-Unit Assessment: September 17/18 End of Unit Assessment: October 1/2 All dates listed are subject to change. Please check the class calendar weekly.
