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
Find ‘F’ when ‘S’ = 81
VERMONT: F = 4 ( S – 65 ) + 10
(The speeding fine in Vermont is $4 for
every mile per hour over the 65 mph limit
plus $10 handling fee.)
CONNECTICUT: F = 10 (S-55) + 40
What is the fine for driving 72 mph?
(Maximum speeding fine in Ct. is $350)
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.
TRANSITION PHASE:
“Mathematics Grade-8” (pre-algebra)
FOCUS: 3 CRITICAL AREAS p.521- 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.)

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.

= 22 – 3x

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

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.

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?
