CCSS Math K-5
Our Objectives:
• To increase K-5 teachers understanding of the Mathematical Practice Standards and the Mathematical Content Standards specific to their grade band.
You would never hear someone say:
I am not very good at reading.
I can’t read.
You do hear people say:
I am not good at math.I can’t do math.
When I was a kid math was my worst subject
What is the difference?
The difference between the USA and other higher performing nations is that a culture of learning math is established from the beginning of a students career in school.
Students are informed and taught everyone can do math.
Essential Question #1
• How do the Mathematical Practice Standards help me to improve my math instruction?
Common Core Standards for Mathematical Practice
1. Make sense of problems and persevere in solving them
2. Reason abstractly and quantitatively3. Construct viable arguments and critique the
reasoning of others4. Model with mathematics5. Use appropriate tools strategically6. Attend to precision7. Look for and make use of structure8. Look for and express regularity in repeated
reasoninghttp://www.corestandards.org/the-standards/mathematics/introduction/standards-for-mathematical-practice

SMP 1 - Make sense of problems and persevere in solving them.
• Students: make sense of the meaning of the task find an entry point or a way to start the task focus on concrete manipulatives before moving
to pictorial representations develop a foundation for problem solving
strategies reexamine the task when they are stuck ask, “Does my answer make sense?”
CCSS Practice #1Practice: #1 Make Sense of problems and persevere in solving them
Three Main Points: Make a Plan Self Monitor and Explain Demonstrate understanding by
corresponding
Example: Student Friendly Definition:I can make a plan, explain my answers, and show how I did it; then I can try another way

What does SMP1 look like in a K-2 classroom?
–“Old” problem (little or no rigor) Tina had 10 balloons. She gave 7 of them away. How many balloons did Tina have then?
–“New” problem (with rigor)Burger Barn has 1 small table that can seat 4 people. They also have 1 large table that can seat double that amount. 15 people came in at lunch time. How many people did not get a seat?
11
SMP 2 - Reason abstractly and quantitatively.
• Students: make sense of quantities and the
relationships decontextualize contextualize use abstract reasoning:
when they measure and compare lengths of objects
when they partition 2-D geometric figures into halves and fourths
as they begin to use standard measurement units
CCSS Practice #2Practice: #2: Reason Abstractly and Quantitatively
Three Main Points: Makes sense of quantities and
their relationship to the problem Bring complementary abilities
together Use reasoning that entails creating
a coherent representation
Example: Student Friendly Definition:I can think about the math problem in my head first
Math StringsMental Math

arguments use definitions and previously
established solutions in their arguments engage in discussions about problem
solving strategies recognize and discuss reasonableness of
strategies recognize and discuss similarities and
differences between strategies
CCSS Practice #3Practice: #3: Construct viable arguments and critique the reasoning of others
Three Main Points: Understand and use stated
assumptions and definitions Construct arguments using
objects, drawings, and actions Listen, read, and critique to find
out what makes sense
Example: Student Friendly Definition:I can make a plan.I can tell my partner how I did it and listen to how they did it too!Talk about it!
Find the Fiction
• My number is 100.1.I can be broken into 4 parts equally2.I represent a millennium3.My quantity in pennies is equal to a
dollar
Find the Fiction
• On your board write the number of the statement that is fiction and write the word fiction next to that number (DO NOT SHOW ANYONE)
• Example: 4 Fiction • When you hear the signal word discuss
with your group one at a time your answer. Come to a consensus
• Answer: 2 is the Fiction • Praise: Expert Thinking
Farmer Fred looks in his field, but can only see feet. He knows that he has four animals. He knows that he has cows and chickens. Farmer Fred sees 14 feet. What are his four animals?
A model of mathematical modeling (pg. 72, CCSSM)
•Identifying important quantities in a practical situation•Making assumptions and approximations to simplify a complicated situation•Mapping relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas•Analyzing relationships mathematically to draw conclusions•Interpreting mathematical results in the context of the situation•Reflecting on whether the results make sense•Improving the model if it has not served its purpose.
23
SMP 4 - Model with mathematics.
• Students: Apply math to solve problems in
everyday life. Represent math by using symbols,
pictures, concrete representation, graphs or equation writing.
Analyze relationships and draw conclusions
Interpret results in context Reflect if results make sense
CCSS Practice #4Practice: #4 Model with mathematics
Three Main Points: Reflect on whether the results
make sense Apply the math they know to
solve problems in everyday life Map relationships using tools
Example: Student Friendly Definition:I can use symbols and numbers to solve problems

• Students: look for patterns and structures in the number
system and other areas of mathematics begin to recognize the commutative property begin to recognize that numbers can be
decomposed into tens and leftovers (ones) work with subtraction as missing addend
problems (How much more do I need to get to ___?)
skip count by tens off the decade to solve addition and subtraction problems
recognize that ten ones equals a ten, and ten tens equals a hundred

Two critical areas in Kindergarten
• In Kindergarten, instructional time should focus on two critical areas:
• (1) representing, relating, and operating on whole numbers, initially with sets of objects (2) describing shapes and space.
• More learning time in Kindergarten should be devoted to number than to other topics.
http://www.corestandards.org/the-standards/mathematics/kindergarten/introduction/
Four critical areas in 1st Grade
• In Grade 1, instructional time should focus on four critical areas:– (1) developing understanding of addition, subtraction,
and strategies for addition and subtraction within 20; – (2) developing understanding of whole number
relationships and place value, including grouping in tens and ones;
– (3) developing understanding of linear measurement and measuring lengths as iterating length units; and
– (4) reasoning about attributes of, and composing and decomposing geometric shapes.
http://www.corestandards.org/the-standards/mathematics/grade-1/introduction/
Four critical areas in 2nd Grade
• In Grade 2, instructional time should focus on four critical areas: – (1) extending understanding of
base-ten notation– (2) building fluency with addition
and subtraction; – (3) using standard units of
measure; and– (4) describing and analyzing
shapes.http; ://www.corestandards.org/the-standards/mathematics/grade-2/introduction/

– Describing and analyzing two-dimensional shapes.
http://www.corestandards.org/the-standards/mathematics/grade-3/introduction/
Three critical areas in 4th Grade
• In 4th Grade, instructional time should focus on three critical areas: – Developing understanding and fluency with multi-digit
multiplication, and developing understanding of dividing to find quotients involving multi-digit dividends.

Essential Question #2
• How will unpacking and chunking the Mathematical Content Standards improve my math instruction?
Key Instructional Shifts
• Focus strongly where the Standards focus
• Coherence: Think across grades, and link to major topics within grades
• Rigor - In major topics, pursue conceptual understanding, procedural skill and fluency, and application with EQUAL intensity
Instructional shift #1
FOCUS strongly where the Standards focus
“… standards must address the problem of a curriculum that is ‘a mile wide and an inch deep.’ These Standards are a substantial answer to that challenge” (CCSS, 2010, p. 3).
Critical AreasThere are 2-4 Critical Areas for
instruction in the Introduction for each grade level
1st Grade Critical Areas – Introduction
They bring focus to the standards at each grade by grouping and summarizing the big ideas that educators can use to build their curriculum and to guide instruction.
–The goal of this activity is to help teachers:Become familiar with the Critical Areas and Content Standards
Understand chunking standards into Critical Ideas (Big Ideas)
Directions
In Grade-level groups, read through the Critical Areas and their descriptions on the Introduction page.
Then, read each of the content standards and mark on the recording sheet with a: X - when a standard strongly matches a Critical Area or
? - when you are not sure
1.OA.1. Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.1
3.OA.1.Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.
Questions to Consider
• Did every standard fall within a Critical Area?
• Are there standards that fall within more than one Critical Area?
• Do all standards within a cluster fall within the same Critical Area?
