Common Core Development

• Initially 48 states and three territories signed on

• Final Standards released June 2, 2010, and can be downloaded at www.corestandards.org

• As of November 29, 2010, 42 states had officially adopted

• Adoption required for Race to the Top funds

Page 3: The Common Core State Standards for Mathematics High School

Common Core Development

• Each state adopting the Common Core either directly or by fully aligning its state standards may do so in accordance with current state timelines for standards adoption, not to exceed three (3) years.

• States that choose to align their standards with the Common Core Standards accept 100% of the core in English language arts and mathematics. States may add additional standards.

Benefits for States and Districts

• Allows collaborative professional development to be based on best practices

• Allows the development of common assessments and other tools

• Enables comparison of policies and achievement across states and districts

• Creates potential for collaborative groups to get more mileage from:– Curriculum development, assessment, and

professional development

Page 6: The Common Core State Standards for Mathematics High School

Characteristics• Fewer and more rigorous. The goal was increased clarity.• Aligned with college and career expectations – prepare all

students for success on graduating from high school.• Internationally benchmarked, so that all students are

prepared for succeeding in our global economy and society.

• Includes rigorous content and application of higher-order skills.

• Builds on strengths and lessons of current state standards.

• Research based.

Page 7: The Common Core State Standards for Mathematics High School

Intent of the Common Core

• The same goals for all students

• Coherence

• Focus

• Clarity and specificity

Page 8: The Common Core State Standards for Mathematics High School

Coherence• Articulated progressions of topics and

performances that are developmental and connected to other progressions

• Conceptual understanding and procedural skills stressed equally

NCTM states coherence also means that instruction, assessment, and curriculum are aligned.

Page 9: The Common Core State Standards for Mathematics High School

Focus

• Key ideas, understandings, and skills are identified

• Deep learning of concepts is emphasized– That is, adequate time is devoted to a topic

and learning it well. This counters the “mile wide, inch deep” criticism leveled at most current U.S. standards.

Page 10: The Common Core State Standards for Mathematics High School

Clarity and Specificity

• Skills and concepts are clearly defined.

• An ability to apply concepts and skills to

new situations is expected.

Page 11: The Common Core State Standards for Mathematics High School

CCSS Mathematical Practices

The Common Core proposes a set of Mathematical Practices that all teachers should develop in their students. These practices are similar to the mathematical processes that NCTM addresses in the Process Standards in Principles and Standards for School Mathematics.

Page 12: The Common Core State Standards for Mathematics High School

CCSS 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.

High School Conceptual Categories

• The big ideas that connect mathematics across high school

• A progression of increasing complexity• Description of the mathematical content to

be learned, elaborated through domains, clusters, and standards

Page 17: The Common Core State Standards for Mathematics High School

Common Core - Domain

• Overarching “big ideas” that connect topics across the grades

• Descriptions of the mathematical content to be learned, elaborated through clusters and standards

Page 18: The Common Core State Standards for Mathematics High School

Common Core - Clusters

• May appear in multiple grade levels with increasing developmental standards as the grade levels progress

• Indicate WHAT students should know and be able to do at each grade level

• Reflect both mathematical understandings and skills, which are equally important

Page 19: The Common Core State Standards for Mathematics High School

Common Core - Standards

• Content statements

• Progressions of increasing complexity from grade to grade – In high school, this may occur over the course

of one year or through several years

Page 20: The Common Core State Standards for Mathematics High School

High School Pathways

• The CCSS Model Pathways are NOT required. The two sequences are examples, not mandates

• Two models that organize the CCSS into coherent, rigorous courses

• Four years of mathematics: – One course in each of the first two years

– Followed by two options for year 3 and a variety of relevant courses for year 4

• Course descriptions – Define what is covered in a course

– Are not prescriptions for the curriculum or pedagogy

Page 21: The Common Core State Standards for Mathematics High School

High School Pathways

• Pathway A: Consists of two algebra courses and a geometry course, with some data, probability, and statistics infused throughout each (traditional)

• Pathway B: Typically seen internationally, consisting of a sequence of 3 courses, each of which treats aspects of algebra; geometry; and data, probability, and statistics.

Conceptual Categories

• Number and Quantity

• Algebra

• Functions

• Modeling

• Geometry

• Statistics and Probability

Page 23: The Common Core State Standards for Mathematics High School

Numbers and Quantity

• Extend the Real Numbers to include work with rational exponents and study of the properties of rational and irrational numbers

• Use quantities and quantitative reasoning to solve problems.

Page 24: The Common Core State Standards for Mathematics High School

Numbers and Quantity

Required for higher math and/or STEM

• Compute with and use the Complex Numbers, use the Complex Number plane to represent numbers and operations

• Represent and use vectors

• Compute with matrices

• Use vector and matrices in modeling

Page 25: The Common Core State Standards for Mathematics High School

Algebra and Functions

• Two separate conceptual categories

• Algebra category contains most of the typical “symbol manipulation” standards

• Functions category is more conceptual

• The two categories are interrelated

Page 26: The Common Core State Standards for Mathematics High School

Algebra

• Creating, reading, and manipulating expressions– Understanding the structure of expressions– Includes operating with polynomials and

simplifying rational expressions

• Solving equations and inequalities– Symbolically and graphically

domain– Use the inverse relationship between

exponents and logarithms and in trigonometric functions

Page 31: The Common Core State Standards for Mathematics High School

Modeling

Modeling has no specific domains, clusters or standards. Modeling is included in the other conceptual categories and marked with a asterisk.

Page 32: The Common Core State Standards for Mathematics High School

Modeling

Modeling links classroom mathematics and statistics to everyday life, work, and decision-making. Technology is valuable in modeling.

A model can be very simple, such as writing total cost as a product of unit price and number bought, or using a geometric shape to describe a physical object.

Page 33: The Common Core State Standards for Mathematics High School

Modeling

• Planning a table tennis tournament for 7 players at a club with 4 tables, where each player plays against each other player.

• Analyzing stopping distance for a car.
