|Standards/Elements: Apply and extend previous understandings of operations with fractions to add, subtract, multiply and divide rational numbers. |

|Essential Question(s): |Enduring Understanding |

|What are negative numbers used for and why are they important? |Negative numbers are used to represent quantities less than zero, e.g. in temperature, scores in |

|Why is it useful for me to know the absolute value of a number? |games and sports, and a loss of income in business |

|What strategies are most useful in helping me develop algorithms for adding, subtracting, multiplying,|Absolute value is useful in ordering and graphing positive and negative numbers. |

|and dividing positive and negative numbers? |Computation with positive and negative numbers is often necessary to determine relationships |

|What properties and conventions do I need to understand in order to simplify and evaluate algebraic |between quantities. |

|expressions? |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: Vocabulary

Sponge Activity:

Week 2 – Topic: Integers, Opposites, Absolute Value

Review Syllabus

Students receive Vocabulary list to study.

Students use scoreboards to play math football game.

T: can compete w/partners or in small groups. Play for 10-15 min. per half. Lesson 4.1, problem 1.

|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.

Early finishers register for GIZMOS, play math games. |Sponge Activity:

Week2- Thurs: Word problem

|Sponge Activity:

Week2 – Friday: Real World

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.

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 | | | | | | | | |Work Session

|Textbook: Finish pg. 196 – 201 and discuss. |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).

Students will share situations in which opposite quantities combine to make zero. | | 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.

| | | | | | | | |Closing

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.
