T HINK 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?

C ONTENT E MPHASIS B Y C LUSTER Take a look at the Content Emphasis in 3 rd Grade. What do you notice? What major clusters are in 3 rd grade? What clusters support the major ones? How do major and supporting clusters differ?

C OOKIE D OUGH T ASK : L OOKING AT S TUDENT W ORK Utilize the rubric to score yourself. Then, exchange your work with someone at your table. Score each others 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?

S TANDARDS FOR M ATHEMATICAL P RACTICE Think about the Cookie Dough task. What mathematical practices were embedded in the task? Todays 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

S TANDARDS FOR M ATHEMATICAL P RACTICE ! 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.

M ODEL WITH M ATHEMATICS 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 L OOK AT THE REAL WORLD Sam Houston Elementary School has nearly 1,000 children from kindergarten through 5 th 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?

L OOK FOR AND M AKE USE OF S TRUCTURE 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

L OOK FOR AND M AKE U SE OF S TRUCTURE Without solving the following which symbol would you put in the blank: (>, <, =) X +5 ________ X + 4 How did you know? This standard involves students thinking about the way things work (mathematical thinking) and applying that to other problems.

L OOK FOR AND E XPRESS R EGULARITY IN R EPEATED R EASONING 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.

U NPACKING THE S TANDARDS Critical AreaCCSSWhat 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

T ASK #1 - C ONSTRUCTING A N A RRAY 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?

T ASK #3 – C OUNTING A ROUND THE C LASS

W HAT 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.

H OW IS FLUENCY WITH MULTIPLES FOSTERED IN YOUR CLASSROOM ?

T ASK #4 – N UMBER L INES FOR M ULTIPLICATION Use a sentence strip or piece of adding machine tape to create a number line from 0 to 30. Above the line, represent skip counting by 5. Below the line, represent skip counting by 6. What do you notice?

T ASK #4 – N UMBER L INES FOR M ULTIPLICATION

A UTHENTIC A SSESSMENT P ROBLEM - P ERFORMANCE T ASK You want to rearrange the furniture in some room in your house, but your parents do not think it would be a good idea. To help persuade your parents to rearrange the furniture you are going to make a two dimensional scale model of what the room would ultimately look like. http://jfmueller.faculty.noctrl.edu/toolbox/examples/seaver/re arrangeroomtask.htm http://jfmueller.faculty.noctrl.edu/toolbox/examples/seaver/re arrangeroomtask.htm

M ULTIPLICATION AND D IVISION - CGI Use the chart provided to sort the problems by problem types that students encounter. When you are done, check your work via Table 2 (p. 89 or 32) in the Common Core. Next, remove the cards and write new problems with your group that correlate with the problem types.

W HAT I S C OGNITIVELY G UIDED I NSTRUCTION (CGI)? Students spend most of their time solving problems related to a book read to them, a unit they have studied, or something going on in their lives Various materials are available to them at all times to assist in problem solving, and each student selects the materials they want to use. Students are not shown how to solve the problems, instead each child solves them in any way that they can, sometimes in more than one way, and reports how the problem was solved to peers and teachers The teacher and peers listen and question the student until they understand the problem solutions, and then the entire process is repeated Using information from students reporting, teachers make decisions about what each child knows and how instruction should be structured to meet each childs needs.

CGI What are some of the Benefits of exposing students to different problem types (CGI)? Which problem type are students least exposed to? Which type supports the Common Cores rigor requirement?

H OMEWORK Read Teaching in Grades 3 and 4: How is each common core state standard for mathematics different from each old objective? Why must we look at the unpacking documents? Why should we look at the crosswalk documents? What are the differences between the old standards and the new Common Core? What are the implications for task work? Why focus on the Standards for Mathematical Practice?

D AY 2 Numbers 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 sections The 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 C LOSER LOOK AT THE READING …. What is the importance of looking at the old standards? Looking at the unpacking,what has changed in 3 rd 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?

S TANDARDS FOR M ATHEMATICAL P RACTICE Standard 2- Reason Abstractly and Quantitatively Standard 5- Use Appropriate Tools Strategically Standard 6- Attend to Precision Peruse above SMP in your CCSS.

F ACT OR F ICTION ? Fraction concepts are difficult. Our students (and many adults) struggle with fraction concepts. What we have been doing isnt working. The Common Core is grounded in research about how students come to understand fraction concepts.

B IG I DEA …. 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

L ET S P ARTITION ! 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!

F OLD 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?

P ARTITIONING K-2: Regions 3: Regions and Number lines 4: Strengthen Number lines, regions beginning to fade 5: Number lines

P ARTITIONING A N UMBER L INE 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 / 6 Describe your process to the person sitting across from you. Prove that the fractions are in the correct location.

P ARTITIONING A N UMBER L INE 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.

P ARTITIONING A N UMBER L INE 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.

W HY N UMBER L INES ? 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.

U NIT F RACTIONS 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.

S YMBOLIC R EPRESENTATION OF F RACTIONS 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.

W HY ARE FRACTIONS DIFFICULT ? Read page 109-110 in Unit 7. What are the big ideas in fraction development? How does the investigations work from this unit aid in developing students understanding?
