PREPARING FOR
THE COMMON CORE STANDARDS: CCSS
ALGEBRA
PRESENTED SUMMER 2011

BE PRO-ACTIVEPREPARE FOR THE CHANGE
• Timeline: implementation & assessment
• What’s different?
• Transition Phase - Today’s Reality:
Pre-Algebra LAST YEAR (gr. 7 - 8) vs CCSS
Algebra THIS YEAR (gr. 8 – 9)
• Mathematical Practices
• Plan: Curriculum, Pacing, Assessments
• Resources: Textbook alignment +++
TIMELINE
Curriculum Assessments
2011-12 K-2 CCSI
2012-13 3-5, HS New NJASK, HSPA
2013-14 6-8 New NJASK, HSPA
2014- K?-Alg. NEW*
• from
• Algebra-EOC test to quarterly benchmarks for all students
3-12 (transition) NJASK, HSPA, SAT2012-13 HS CCSI NJASK, HSPA, SAT
3-5 CCSI2013-14 6-8 CCSI NJASK, HSPA
ASSESSMENT
Measure standards that are rigorous, globally competitive, and consistent across the states.
New Jersey’s choice
The assessment consortium PARCC (Partnership for Assessment of Readiness for College and Careers)
New assessments will replace current state NCLB tests in 2014-2015.
WHAT DOES THIS MEAN TO YOU?
TRANSITION YEAR(S)
CONTENT
• CCSS Skills not mastered in PreAlgebra
• Grade-8: NJASK8 standards not in CCSS
• Grade-9: HSPA/SAT content not in CCSS
PROCESS
• Conceptual understanding of content
• Applying skills in real-world situations
• New vocabulary
OLD EXPECTATIONS
(The speeding fine in Vermont is $4 for every mile per hour over the 65 mph limit plus $10 handling fee.)
(Maximum speeding fine in Ct. is $350)
CONNECTICUT: F = 10 (S-55) + 40 What is the fine for driving 72 mph?
Find ‘F’ when ‘S’ = 81VERMONT: F = 4 ( S – 65 ) + 10
NEW EXPECTATIONS
1. Describe the speeding fine in words.
2. In Connecticut at what speed does it no longer matter?
3. At 80 mph how much better off would you be in VT than in CT?
4. Use a graph to show this difference.
FOCUS: 3 CRITICAL AREAS p.52-
1- Formulate and reason about expressions & equations
2- Grasp the concept of function and using functions to describe relationships
3- Analyze 2 and 3-dimensional space/figures (distance, angle, similarity, congruence; understand and apply the Pythagorean Theorem.)
TRANSITION PHASE: “Mathematics Grade-8” (pre-algebra)
TRANSITION PHASE: 5 DOMAINS
Mathematics Grade-8 Overview (p.53)(pre-algebra)
1. The Number System
2. Expressions and Equations
3. Functions
4. Geometry
5. Statistics and Probability
EXPRESSIONS
Price plus 6% sales tax
Perimeter:L
WW
L
p + .06p or p(1.06)
L + w + L + wL + L + w + w 2(L) + 2(w) 2(L + w)
CREATE EQUATIONS
CREATE * REPRESENT * REARRANGE
1. Create equations in 2 or more variables to represent relationships:
A line going through (2,5) (-3,8)
2. Create an inequality:
The car and insurance payments cannot exceed 8% of her income.
3. Rearrange Ohm’s law:
V = IR to highlight resistance R
REASON WITH EQUATIONS
Explain each step in solving a simple equation.
8x + 2(x-6) = 16 – 3(x-2)
1. 8x + 2x – 12 = 16 – 3x +6
2. 10x - 12 = 22 – 3x
3. 13x - 12 = 22
4. 13x = 34
SOLVE (PRE-ALGEBRA)
EQUATIONS in one variable (w/coefficients represented by letters)
ab + c = d Solve for b.
SYSTEMS 8.EE8.a.b.c. (p.55)
Does the line through (2,6) and (3,5) intersect with the line going through points (4,8) and (2,4)?
EXPLAIN or model how you know!
SAMPLE 8.EE (PRE-ALGEBRA)
Work with radicals and integer exponents.
1. Know and apply the properties of integer exponents to generate equivalent numerical expressions.
For example,
32 x 3-5 = 3-3 = 1/33 = 1/27
GRADE-8 (PRE-ALGEBRA) Overview (p.53)
• Number Sense
• Expressions & Equations
• Functions
• Geometry
• Statistics & Probability
ALGEBRA Overview (p.57)
• Seeing Structure in Expressions
• Arithmetic w/Polynomials & Rational Expressions
• Creating Equations
• Reasoning w/Equations & Inequalities
Use the CCSS Grade-8 PRE-ALGEBRA STANDARDS
Middle School – think grade-7 students
HS – think grade-8 students

FORMAT ALGEBRA STANDARDS:
DOMAIN: A-SSE Seeing Structure in Expressions
CLUSTER: Interpret the structure of expressions
STANDARD:
1. Interpret expressions that represent a quantity in terms of its context.
a. Interpret parts of an expression (terms, factors, coefficients)
b. Interpret complicated expressions by viewing one or more of their parts as a single entity. Interpret P(1+r)n as the product of P and a factor not depending on P.

REASONING & SENSE MAKING
PROBLEM-SOLVING ACTIVITY
What is the perimeter of this shape? (long bars represent ‘x’, squares are 1 x 1)
WORK ALONE; SHARE STRATEGIES with your GROUP
Why is this a good REASONING & SENSE MAKING task?
OVERARCHING MATHEMATICAL PRACTICES
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
AS THE CROW FLIES
STUDENT ACTIVITY SHEET
(Beginning Algebra) NCTM
Suppose that the city in which you live has a system of evenly spaced perpendicular streets forming square city blocks. The map below shows your school; your house, which is located two blocks west and five blocks north of the school; and your best friend’s house, which is located eight blocks east and one block south of the school.
See questions 1-5 on pages 20-21
MAXIMIZING AREA
BEGINNING ALGEBRA (p.30-31)
Question 1. What happens to the perimeter and area when you begin with a rectangle, cut a strip off the rectangle, and rearrange this piece to form a new figure as shown?
