The DeKalb County School System The Department of Middle School Instruction Standards-based Lesson Plan Week 2 08/17/15 - 08/21/15 Standards/Elements: Apply and extend previous understandings of operations with fractions to add, subtract, multiply and divide rational numbers. Essential Question(s): What are negative numbers used for and why are they important? Why is it useful for me to know the absolute value of a number? What strategies are most useful in helping me develop algorithms for adding, subtracting, multiplying, and dividing positive and negative numbers? What properties and conventions do I need to understand in order to simplify and evaluate algebraic expressions? Enduring Understanding Negative numbers are used to represent quantities less than zero, e.g. in temperature, scores in games and sports, and a loss of income in business Absolute value is useful in ordering and graphing positive and negative numbers. Computation with positive and negative numbers is often necessary to determine relationships between quantities. Models, diagrams, manipulatives and patterns are useful in developing and remembering algorithms for computing with positive and negative numbers. Properties of real numbers hold for all rational numbers. Positive and negative numbers are often used to solve problems in everyday life .

Take One: Cloze Notes Sponge Activity: Week2-Tues: Let’s Get Started…What do you know about integers and absolute value? And one convert fraction to decimal (practice/review) STAR TESTING (not for a grade) – COMPUTER LAB Every student is tested to determine strengths and weaknesses to guide our instruction this year. Sponge Activity: Week2- Thurs: Word problem Use discovery, guided notes or ppt to add & sub rational numbers. Explain add using 3 ways: algorithms, #lines and 2 color counters. Include opposites, additive inverses and zero pairs. Early finishers register for GIZMOS, play math games. Students use scoreboards to play math football game. T: can compete w/partners or in small groups. Play for 1015 min. per half. Lesson 4.1, problem 1. Work Session Textbook: Finish pg. 196 – 201 and discuss. Sponge Activity: Week2 – Friday: Real World Model zero pairs then model 4 in several ways using zero pairs then have students model -3 in several ways using zero pairs. Check for understanding Review of Integers: Math Antics Lesson Video Students complete guided Cloze notes as view the video. Guided notes on integers and absolute value, adding and subtracting rational numbers (use integer notes and/or power points). Build on learning from football game of Monday, to Add & Subtract Integers: Math Antics Lesson Video on Add & Subtract Integers Students complete guided Cloze notes as view the video. Students will practice adding rational numbers limit to integers by walking the line Complete lesson 4.3 text thru pg. 223 Guided notes on integers and absolute value, adding and subtracting rational numbers (use integer notes and/or power points). Write number sentences. Students will share situations in which opposite quantities combine to make zero. Closing HW: 1. Textbook Lesson 4.1 Skills Practice, page 489. 2. Vocabulary: Study 1st 7 words (integer through rational numbers.) TOD—Complete 1 of 3 when asked. 1.Why is the absolute value of a number positive? 2. Name 2 numbers with the same absolute value 3. Name 3 types of integers HW: 1. Complete guided practice 10-1, Odds 2. Absolute Value handout 3. Vocabulary: study next three words on list (counters, multiplicative inverse, absolute value) Wrap-up: students will verbalize the correct way to solve addition problems with integers using a number line HW: Lesson 4.2 Skills Practice #10-20, ODDS Vocabulary: Study last 4 words on vocabulary sheet. (Terminating decimals to Bar notation.) Compare results from classwork HW: Finish lesson 4.3 or assign skills practice 4.3 if needed. Review notes, powerpoints, etc for week. Be prepared to demonstrate understanding of vocabulary words introduced
