Due Dates • Due Dates versus Lectures Hawkes • Software • SMART Math Lab Reading Guides • • • • Found on my directory web site Print out and COMPLETE before class Due at the beginning of class No late reading guides will be accepted Class Notes • May be used to complete Exit Tickets • May be used for Quizzes • May be used to Review for Tests Topics from your past…Ch 1 • • • • Fractions operations (+ - X / ) Rounding decimals – place names Decimal to percent to fraction Order of Operations: PEMDAS (MD, AS left to right as a grouping) • Factoring: • Prime & Composite numbers • Primes: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47 • Prime Factorization (make tree) • Least Common Multiple (LCM) • Ex: find the LCM of 2, 5, 6, 9 • LCM=90 The Real Number Line and Inequalities 1.1a Real Number Classifications • Real Numbers: the numbers found on a Number Line Hawkes slide 11 • Irrational Numbers: decimals repeating without a pattern (pi, e, non-perfect square roots) • Rational Numbers: zero, non-decimals, fractions, repeating decimals, perfect squares • Integers: positive/negative non-decimal numbers, zero • Whole Numbers – zero, positive integers • Natural (counting) Numbers – positive integers • • Example: Classify 7 in the Real Number System Try it… Classify -1/2 in the Real Number System Number Line • Draw a number line • Label the number line • Plotting points Inequalities • Inequality Symbols – Hawkes slide 17 • Read either left to right or right to left • Example: show on a number line all x 2 • Comparing fractions: rewrite with a common denominator if you can’t determine • Example: Graph and compare ¾ and 2/3 Try it… • Show on a number line all x 4 5 2 • Graph and compare and 7 3 Absolute Value 1.1b Absolute Value • Absolute Value: the distance from zero on number line • Example: Use a number line to show |5| |-3| • What about… | 4 | Absolute Value of a Variable • Variable: a letter whose value may change • | x | 8 What values of x make this true? • What about… | x | 10 Graphing Absolute Value • Example: Graph the solution: | x | 3 • Example: Graph the solution: | x | 7 • Try it… Graph the solution: | x | 5 Summary • • • • Due Date Sheet Lecture Calendar SMART Math Lab Reading Guides Coming up… • Day 2 Adding & Subtracting with Real Numbers • Quiz #1 – Due by Friday (SMART Lab) • Reading Guide for Day 2: – Instruct Sections 1.2-1.3 – Email [email protected] if you have any problem getting into Blackboard – I will send a copy Exit Ticket On a clean sheet of paper put your full name, today’s date and the label “Sections 1.1a – 1.1b” Using your class notes as a review, copy down these problems and clearly show your answers. 8 1. Classify in the Real Number system. 9 2. Graph the solution (careful!): | x | 7
