THINK ABOUT A PRESENT….
If you took something old from your house and wrapped it in a new box with a shiny bow, does it make it a new gift?
Likewise, taking the old NCSCOS and squeezing it into the new Common Core will not change the face of education.
How do you think the Common Core will change math instruction?
CONTENT EMPHASIS BY CLUSTER
Take a look at the Content Emphasis in 3rd Grade. What do you notice?

4. Jermaine’s mother loves oatmeal cookies. She has $20 to spend. What is the greatest number of tubs of oatmeal cookie dough she can buy? Explain how you figured this out.
COOKIE DOUGH TASK:LOOKING AT STUDENT WORK
Utilize the rubric to score yourself. Then, exchange your work with someone at your table. Score each other’s work using the rubric.
What information did you gain about students’ understanding via the task and rubric?
What would your “next steps” be instructionally after utilizing this task?
STANDARDS FOR MATHEMATICAL PRACTICE
Think about the Cookie Dough task. What mathematical practices were embedded in the task?
Today’s Focus…
Standard 4- Model with Mathematics Standard 7- Look for and Make use of Structure Standard 8- Look for and Express Regularity in
Repeated Reasoning
STANDARDS FOR MATHEMATICAL PRACTICE!
Peruse the MP4, MP7, & MP8 located at the beginning of your Common Core State Standards.
On a sticky note and in your own words… Write a word, phrase, or sentence and/or draw
a picture/caption that best describes each practice.
Post your sticky notes onto the relative charts around the room.
MODEL WITH MATHEMATICS
Calls for students to interact with their everyday world through “play” and to explore the mathematics. Think about size, shape and fit, quantity, and
number. Students should begin to understand that
“mathematics is not just a collection of skills whose only use is to demonstrate that one has them.”
Ensure that the mathematics that students are engaged in helps them see and interpret the world.
A LOOK AT THE REAL WORLD
Sam Houston Elementary School has nearly 1,000 children from kindergarten through 5th grade, with about the same number of students in each grade. No class has more than 25 students, but most classes are close to that. What can you figure out from this information?
How does this problem allow students to Model with Mathematics?
LOOK FOR AND MAKE USE OF STRUCTURE
Think about how students are typically taught to add fractions with a like denominator.
How is that different from the following:If 2 sheep plus 3 sheep is 5
sheep and two hundred plus three hundred equal 5 hundred, then would 2/8 + 3/8 = 5/8
LOOK FOR AND MAKE USE OF STRUCTURE
Without solving the following which symbol would you put in the blank:
(>, <, =)X +5 ________ X + 4How did you know?
This standard involves students thinking about the way things work (mathematical thinking) and applying that to other problems.
LOOK FOR AND EXPRESS REGULARITY IN REPEATED REASONING
Choose three numbers in a row (5, 6, 7 for example).
Compare the middle number times itself to the product of the two outer numbers.
Do this several times, then without solving tell what the answer is to 29 x 31.
Explain the pattern in the problem to a partner.
A CLOSER LOOK AT THE PRACTICES
Looking back at the cookie dough task, what practices were evident?
Watch the following video. Record when and how the
teacher uses practices 4, 7, and 8.

UNPACKING THE STANDARDSCritical Area CCSS What does it say in your
own words?By the end, what can
students do?Give an example of a task in a lesson or assessment.
Developing Understanding of multiplication and
division strategies for multiplication and division within 100
3.OA.3- Use multiplication and
division within 100 to solve word problems in
situations involving equal groups, arrays, and
measurement quantities
3.OA.4- Determine the unknown whole number
in a multiplication or division equation relating
three whole numbers.
3.OA.5- Apply properties of operations as strategies
to multiply and divide
3.OA.7- fluently multiply and divide within 100, using strategies such as the relationship between
multiplication and division
TASK #1 - CONSTRUCTING AN ARRAY
•Build a 6 x 3 array using colored tiles (in one color). What is the product (number of tiles)? •Use the 6 x 3 array to build a 6 x 9 array (possibly another color). •How did a 6 x 3 array help you figure out the product of 6 x 9?
TASK #1
TASK #2 – QUICK IMAGESDRAW WHAT YOU SEE. WRITE AN EQUATION.
TASK #3 – COUNTING AROUND THE CLASS
Count around the class by 4’s.
What would be a multiplication equation that would represent 6 people counting by 4’s?
Predict what the 10th person say? the 20th? Turn and tell… Explain your reasoning to a partner.
What is the value of this activity? (p. 155, lesson 1.3)
TASK #3 – COUNTING AROUND THE CLASS
WHAT DOES FLUENCY REALLY MEAN? Efficiency implies that the student does not get bogged
down in too many steps or lose track of the logic of the strategy. An efficient strategy is one that the student can carry out easily, keeping track of subproblems and making use of intermediate results to solve the problem.
Accuracy depends on several aspects of the problem-solving process, among them careful recording, knowledge of number facts and other important number relationships, and double-checking results.
Flexibility requires the knowledge of more than one approach to solving a particular kind of problem, such as two-digit multiplication. Students need to be flexible in order to choose an appropriate strategy for the problem at hand, and also to use one method to solve a problem and another method to double-check the results.

DAY 2Numbers and Operations Fraction
Mayor Mason has raised money for a new park that is 800 yd by 800 yd. He divides the park into various sections:He starts by dividing the park into 4 square sections.The NE section is divided into 8 equally-sized triangular
sectionsThe NW section has 2 triangular sections and 2
rectangular sections, and all 4 sections are the same size
The southeast section has 16 equally sized square sections
The southwest section has 2 equally-sized triangular sections that together make up 1/3 of the section, 4 equally-sized rectangular sections that together make up 1/6 of the section, and equally-sized rectangles that make up the rest of the southwest section.
For each section, find its area as a fraction of the entire region.
A CLOSER LOOK AT THE READING….
What is the importance of looking at the old standards? Looking at the unpacking ,what has changed in 3rd grade with regards to fraction development?
How does the CCSS differ from the NCSCOS with regards to teaching and expectations?
According to p. 501, what are the implications for task work within the common core?
According to the article, what are the implications for the Standards for Mathematical Practice?
STANDARDS FOR MATHEMATICAL PRACTICE
Standard 2- Reason Abstractly and Quantitatively
Standard 5- Use Appropriate Tools Strategically Standard 6- Attend to Precision
Peruse above SMP in your CCSS. Summarize each on a sticky note using a
picture/caption, phrase, or sentence. Post onto charts.
GALLERY CRAWL!
REASON ABSTRACTLY AND QUANTITATIVELY
Write as many numerical expressions as you can that describe the tiles in this figure.
Did you have- 1+2+3+4+3+2+1 or 1+3+5+7 or 10 +6What about this? 8 + 8
How many busses are needed for 99 children if each bus seats 44?
If the child can solve and get 2 r 11, 2 ¼ or 2.25, they have AN answer. But if they can take that answer and reason/interpret that 3 buses are needed, then they are reaching this standard (MP2).

Converted to common denominators Compared to 1/2 or 50%, or 1 or 100%
(e.g., 5/6 is more than 1/2 and 3/8 is less than 1/2)
Explained that eighths are smaller than sixths and there are fewer eighths
Converted to decimals or percents Gave other reasonable explanation Guessed, did not explain, or gave
faulty explanation
USE APPROPRIATE TOOLS STRATEGICALLY
Requires the classroom to be comprised of choice tools readily available for problem solving
Calls for students to develop the ability to make sound decisions about when each of these tools might be helpful, recognizing both the insight to be gained and their limitations
Think about the following tools: Number line, hundreds board, color tiles When would it be helpful to use these and when
might it be limiting?
ATTEND TO PRECISION The focus of this standard is not only about
accurate calculations (correct answer), but about precision of communication in: Speech Written symbols, and In specifying the nature and units of quantities

By the end, what can students do?
Give an example of a task in a lesson or assessment.
Developing understanding of
fractions, especially unit fractions (fractions with
numerator 1)
3.NF.1- Understand a fraction 1/b as the
quantity formed by 1 part when a whole is
partitioned into b equal parts; understand a fraction a/b as the
quantity formed by a parts of size 1/b

3.NF.3- Explain equivalences in special
cases, and compare fractions by reasoning
about their size
FACT OR FICTION?
Fraction concepts are difficult.
Our students (and many adults) struggle with fraction concepts.
What we have been doing isn’t working.
The Common Core is grounded in research about how students come to understand fraction concepts.
BIG IDEA….
The first goal in the development of fractions should be to help children construct the idea of fractional parts of the whole- the parts that result when the whole or unit has been partitioned into equal sized portions or fair shares. – John Van de Walle
LET’S PARTITION!
With your partner, fold one plate so that each of you get the same amount.
Did you get equal amounts? How do you know? Prove it!
FOLD AND FOLD AGAIN!
You and your partner would like two pieces each.
So, fold another plate so each of you get two equal pieces.
How did you fold the plate? Did you each get equal shares? How do you know? Prove it!
What do we call these equi-sized portions?
How is the process of folding halves similar/different from folding fourths?
HOW DO WE MAKE FOURTHS?
“Half of a half” concept
STUDENTS NEED TO PARTITION UNMARKED REGIONS (NO LINES ALREADY DRAWN).
WHY?
PRE-PARTITIONED REGIONS LEAD TO A COMMON MISCONCEPTION:
¼
1/3
DIVIDING THE ROOM
You want to share the space in your school closet between you and three other teachers. On grid paper, draw three 6x4 rectangles and label them a. b. and c. Divide each “closet” according to the directions below:a) 2 sections are rectangles and 2 sections
are different shaped rectanglesb) 2 sections are rectangles and 2 sections
are triangles
c) You have 4 different shaped regions

Marilyn is serving strawberry ice cream. Each scoop contains 1/4 of a cup. By the end of her first shift, she has scooped out 4 servings. How much ice cream has she served?
Solve the School Carnival tasks on your table.
Represent your solutions on a number line and model each with an equation.
Glow sticks are a popular carnival prize. A box of glow sticks weighs ¼ of a pound. If I am carrying 7 pounds, how may boxes am I carrying?

PARTITIONING
K-2: Regions
3: Regions and Number lines
4: Strengthen Number lines, regions beginning to fade
5: Number lines
PARTITIONING A NUMBER LINE
Make a number line from 0 to 2.
Put the following fractions on the number line
1/6, 2/6, 5/6, 6/6, 8/6, 11/6Describe your process to the person sitting across
from you.
Prove that the fractions are in the correct location.
PARTITIONING A NUMBER LINE
Using your number line, solve:You need 1 5/6 yards of ribbon for a
school project. You find 5/6 in your closet, and ask your mom to buy 5/6 more.
Do you have enough? If not, how much more do you need? If so, how much ribbon will you have left over? Be able to explain using your number line.
PARTITIONING A NUMBER LINE
Create another number line 0 to 2 Plot the following numbers:
1/3, 3/4, 4/3,
2/3 , 3/2
In between each of your fractions, plot another fraction (you should have 9 fractions)Describe your process to
the person sitting across from you.
Prove that the fractions are in the correct
location.
WHY NUMBER LINES?Easier to divide the whole into equal parts because only length is involved.
Addition and subtraction are much more easily modeled.
Multiplication and Division are more easily modeled.
UNIT FRACTIONS
Unit fractions are the basic building blocks of fractions, in the same sense that the number 1 is the basic building block of whole numbers.
Every fraction is a piecing together of unit fractions (2/5 is 2 copies of the unit fraction 1/5).
3NF
2. Understand a fraction as a number on the number line; represent fractions on a number line diagram.
Represent a fraction 1/b on a number line diagram by
defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
Represent a fraction a/b on a number line diagram by
marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
SYMBOLIC REPRESENTATION OF FRACTIONS
Students must be able to think about fractions in a different way than when they are working with whole numbers.
The number 34 is viewed as representing a specific quantity. When the same digits (3 and 4) are used in the number ¾, the digits are representing a part/whole relationship.
WHY ARE FRACTIONS DIFFICULT?

STANDARDS FOR MATHEMATICAL PRACTICE
Standard 1- Make Sense of problems and persevere in solving them
Standard 3- Construct Viable Arguments and Critique the Reasoning of Others
STANDARDS FOR MATHEMATICAL PRACTICE
Peruse the MP1 & MP3 located at the beginning of your Common Core State Standards.
On a sticky note and in your own words…
Write a word, phrase, or sentence and/or draw a picture/caption that best describes each practice.
Post your sticky notes onto the relative charts around the room.
MAKE SENSE OF PROBLEMS AND PERSEVERE IN SOLVING THEM
Problem Solvers must: Figure out the right question to be asking What relevant experience we have What additional information we might need And know where to start
In addition we must have the stamina to continue even when progress is hard, but enough flexibility to try alternative approaches when progress seems too hard
MAKE SENSE OF PROBLEMS AND PERSEVERE IN SOLVING THEM
How does this questioning approach aid in developing this skill for our students: Eva had 36 green pepper seedlings and 24
tomato seedlings. She planted 48 of them. What questions could be figured our from that information?
CONSTRUCT VIABLE ARGUMENTS AND CRITIQUE THE REASONING OF OTHERS
In writing we say, show don’t tell. However, this standard require our students to Show and Tell.
Appropriate representations will help students to defend or justify their answers.
Example:How many different 5” tall towers of 1” cubes can be
made, using exactly one white cube and four blue cubes?
How could students construct an argument via this question?
WHAT DOES THIS LOOK LIKE?
