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: Vocabulary
Sponge Activity:
Week 2 – Topic: Integers,
Opposites, Absolute Value
Review Syllabus
Students receive Vocabulary
list to study.
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).
