mathematics tools for the 21 st century classroom
Mathematics Tools for the 21st Century Classroom
  • U.S. Secretary of Education Arne Duncan at NCTM Annual Meeting, 15 April 2011
  • “Curricular materials cover so much ground too superficially, failing to provide students with an understanding of the concepts that are essential for success.”
  • “Tests don’t always measure what’s important, or provide information back to you to help you improve.”

  • Common Core State Standards for Mathematics
  • An opportunity to address…
    • Competitiveness
    • Fulfillment
common core standards
Common Core Standards
  • Sponsored by the Council of Chief State School Officers (CCSS) and the National Governors Association (NGA)
  • First significant attempt to systematically align K-12 standards across the U.S.
  • Building on NCTM’s standards documents from 1980, 1989, 2000, 2006, and 2009
  • NCTM among groups providing feedback
common core standards18
Common Core Standards
  • Different from most current state standards
  • Based on most recent research regarding students’ learning trajectories related to mathematics content
  • Includes detailed description of the way mathematics is learned and used by students (Mathematical Practice)
common core development
Common Core Development
  • Initially 48 states and three territories signed on
  • As of April 1, 2011, 41 states have officially adopted (plus DC and US VI)
  • Final Standards released June 2, 2010, at www.corestandards.org
  • Adoption required for Race to the Top funds
common core development20
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 to the common core standards accept 100% of the core. States may add additional standards.
benefits for states and districts
Benefits for States and Districts
  • Allows collaborative professional development based on best practices
  • Allows development of common assessments and other tools (SC in SMARTER Balanced and PARCC)
  • Enables comparison of policies and achievement across states and districts
  • Creates potential for collaborative groups to get more economical mileage for:
    • Curriculum development, assessment, and professional development

CCSSM stands for

Common Core State Standards for Mathematics

Arne Duncan at NCTM
  • “... today’s tests don’t measure higher-order thinking skills or deep understanding of subject material. American students deserve better than the fill-in-the-bubble tests that are now common across states.”
  • New assessments “… are the ones that you’ve longed for. They will measure critical thinking skills and complex student learning.”
  • Fewer and more rigorous
  • Aligned with college and career expectations
  • Internationally benchmarked
  • Rigorous content and application of higher-order skills.
  • Builds on strengths and lessons of current state standards.
  • Research based
intent of the common core
Intent of the Common Core
  • The same goals for all students
  • Coherence
  • Focus
  • Clarity and Specificity
  • 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

  • Key ideas, understandings, and skills are identified
  • Deep learning of concepts is emphasized
    • That is, time is spent on a topic and on learning the topic well. This counters the “mile wide, inch deep” criticism leveled at most current U.S. standards.
clarity and specificity
Clarity and Specificity
  • Skills and concepts are clearly defined
  • Being able to apply concepts and skills to new situations is expected
  • Word Cloud
ccssm mathematical practices
CCSSM Mathematical Practices
  • Common Core includes a set of Standards of Mathematical Practices that all teachers should develop in their students.
  • Similar to NCTM’s Mathematical Processes from the Principles and Standards for School Mathematics.
  • Practices MUST be assessed
8 ccssm mathematical practices
8 CCSSM Mathematical Practices
  • Make sense of problems and persevere in solving them.
  • Reason abstractly and quantitatively.
  • Construct viable arguments and critique the reasoning of others.
  • Model with mathematics.

common core format
Common Core Format

Domains are large groups of related standards. Standards from different domains may sometimes be closely related. Look for the name with the code number on it for a Domain.

Common Core Format

Clusters are groups of related standards.Standards from different clusters may sometimes be closely related, because mathematics is a connected subject.

Clusters appear inside domains.

Standards define what students should be able to understand and be able to do – part of a cluster.

format of k 8 standards49


Format of K-8 Standards




common core domain
Common Core - Domain
  • Domains are overarching big ideas that connect topics across the grades
  • Descriptions of the mathematical content to be learned elaborated through clusters and standards
common core standards52
Common Core - Standards
  • Standards are content statements. An example content statement is: “Use properties of operations to generate equivalent expressions.”
  • Progressions of increasing complexity from grade to grade
common core clusters
Common Core - Clusters
  • May appear in multiple grade levels in the K-8 Common Core. There is increasing development as the grade levels progress
  • What students should know and be able to do at each grade level
  • Reflect both mathematical understandings and skills, which are equally important
high school conceptual categories
High School Conceptual Categories
  • The big ideas that connect mathematics across high school – such as Functions or Probability and Statistics
  • A progression of increasing complexity
  • Description of mathematical content to be learned elaborated through domains, clusters, and standards
high school pathways
High School Pathways
  • The CCSSM Model Pathways are two models that organize the CCSSM into coherent, rigorous courses
  • The CCSSM Model Pathways are NOT required. The two sequences are examples, not mandates
high school pathways56
High School Pathways
  • Four years of mathematics:
    • One course in each of the first two years
    • Followed by two options for year three and a variety of relevant courses for year four
  • Course descriptions
    • Define what is covered in a course
    • Are not prescriptions for the curriculum or pedagogy
high school pathways57
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 that consists of a sequence of 3 courses each of which treats aspects of algebra, geometry and data, probability, and statistics.

  • An Opportune Time to Consider Integrated Mathematics March, 2011
  • “Students need to see mathematics as an integrated whole, with connections across the content domains...
  • …the United States will never show well in international comparisons of mathematics performance as long as other countries have an integrated mathematics, and we take a “layer cake” approach.
  • … we have an unprecedented opportunity… to integrate the content of our secondary mathematics…”
promising opportune but perfect
Promising, Opportune… but Perfect?

Problem areas:

  • CCSSM has never been field tested
  • Can the assessments address understanding and measure the Practices?
  • How to accommodate exceptional learners?
  • Learning trajectories require careful vertical articulation
not perfect
Not Perfect …

Problem areas:

  • Too little technology particularly in K-8
  • No statistics in K-5
  • How can this be 21st Century competitive?
  • Piling on in Grade 6
ideal according to ed
Ideal (according to Ed)
  • CCSSM as standards and not mandated curriculum
  • Give districts choices for implementation (avoiding a lock-step approach)
  • Assessment includes parts addressed by teachers at the local level (as in Europe)
  • Reward success, don’t punish non-success
  • TRUST teachers to do the work we hire them to do
  • We don’t buy a dog, then bark for it.
  • Invest in the best pre- and in-service teacher development….
  • Then get out of the way and let teachers do what these very intelligent professionals were educated to do (Finland)
beaufort core vision for stem
Beaufort CORE Vision for STEM
  • An investment in the education of high quality teachers
