Intro to High School Teaching and Learning Resources

Common Core Math

Educators across the country in states that have adopted the Common Core State Standards for Mathematics need teaching and learning resources that pair with the goals of the standards.

Star with word Free on it"Free" and low-cost with high quality are key words.  The good news is that the Web has multiple sites from which to select resources.  However, one needs to know where to look.  That's where CT4ME comes in as a prime source.

CT4ME has taken on the challenge to identify specific resources that are aligned to or can be used to address each cluster of the CCSS high school math standards.  Resources are intended to enhance instruction and to provide group and individual learning experiences for achieving the goals of the standards.

Common Core Math Book Bundle: Strategies for Common Core Mathematics: Implementing the Standards for Mathematical Practice, 9-12 (Strategies for the Common Core Mathematics) by Texas & JonesWithin each cluster for number and quantity, algebra, functions, geometry, and statistics and probability you will find technology investigations, multiple choice and constructed response exercises, and performance tasks.  The standards for mathematical practice, as they apply, are noted within many of those resources.  Additionally, the 2013 book by Leslie Texas and Tammy Jones, Common Core Math Book Bundle: Strategies for Common Core Mathematics: Implementing the Standards for Mathematical Practice, 9-12 (Strategies for the Common Core Mathematics), will benefit math educators.  It explains "each of the eight mathematical practices and gives high school educators specific instructional strategies that align with the Common Core State Standards for Mathematics."

Vocabulary Building:

CT4ME recommends that learners develop math vocabulary by creating their own vocabulary cards to include the word, its definition in their own words, examples and non-examples of the word, and characteristics and facts about the word, such as would be found using the Frayer Model.

Frayer Model




Word or Concept



Vocabulary for the Common Core by Marzano & SimmsVocabulary for the Common Core by Robert Marzano and Julie Simms (2013) will help educators to incorporate CCSS vocabulary into teaching and learning.  Among its goals is for readers to be able to make general academic and domain specific language from the CCSS relevant to students.

Granite School District in Salt Lake City, Utah, includes math vocabulary organized by grade level (K-7 and secondary including for the Common Core standards, and dual immersion) and resources for teaching vocabulary development.  Select the following for the secondary level, which match the Common Core:

  • Vocabulary Secondary A-L
  • Vocabulary Secondary M-Z features "terms and formulas from beginning algebra to calculus."  Terms include appropriate pictures, diagrams, tables, and examples and are indexed by subject area: numbers and symbols; sets, logic, proof; geometry, algebra, trigonometry, advanced algebra and precalculus, calculus, advanced topics, probability and statistics, real world applications.  Entries that feature multimedia are noted.

Question mark Are your students ready for the Common Core math exams?

You can find out by using Benchmark Now!, a free online tool from Naiku for Grades 3-High School.  It is designed to help identify students' knowledge and skills with professionally developed assessments using questions from Houghton Mifflin Harcourt’s Assess2Know® Benchmark Item Bank.  Questions in the item bank are aligned to Common Core State Standards.  There are beginning-of-year assessments help identify students’ readiness by domain and multiple interim assessments for each grade.  Domain specific assessments provide teachers insight into student performance by standard.

For testing in your state and sample test items, see our CT4ME section for Standardized Test Preparation.

Do you want to make parents more aware of the Common Core standards and how they can help their children?

The Council of the Great City Schools produced Parent Roadmaps to the Common Core Standards- Mathematics in 2012 and 2013 for grades K-8 and high school to help provide guidance to parents about what their children will be learning and how they can support that learning. The publications also include three-year snapshots showing how selected standards progress from year to year so that students will be college and career ready upon their graduation from high school.

ASCD Policy Points (2013, October) dispels rumors and myths surrounding the CCSS, so that parents, educators, policymakers, and the general public have a better understanding of what the standards are and are not.  Read Common Core State Standards--Myths and Facts.


PARCC and SBAC Testing Information

PARCC Assessments and Practice Tests:

The Partnership for Assessment of Readiness for College and Careers (PARCC) includes a series of common policies related to assessment administration, scoring and the reporting of Common Core test results.  There is also a section that addresses accessibility and test accommodations for learners with disabilities and English language learners.  You'll also find released test items.

See PARCC.Pearson for Pearson Access, your technology set-up requirements, manuals and training, test preparation (sample items, tutorials, practice tests), bulletins, and support.  The math practice tests are available in computer based and print formats for each grade 3-8, algebra 1, algebra 2, geometry, and integrated pathway.

PARCC Test Administration Portal lists Mathematics Guidance and Policies, including the following:

  • The PARCC Calculator Policy indicates for high school that a student may use "Graphing calculators with functionalities consistent with TI-84 or similar models. (Student may also bring a scientific calculator or a four-function with square root and percentage functions.)" (2012, 2016 update, p. 1).  [Note: TI Math includes multiple activities for using the TI-84 calculator with learners.  Activities are grouped by content area: Algebra I, Geometry, Algebra 2, Precalculus, Calculus, and Statistics.]
  • PARCC's High School Assessment Reference Sheet (2016) will also be helpful to learners, as it contains key measurements and algebra and geometry formulas.

Learners who will take the PARCC assessment should be aware of how their performance will be reported.  In July 2013, the Partnership for Assessment of Readiness for College and Careers (PARCC) released its Contents of the Grade- and Subject-Specific Performance Level Descriptors (PLDs) in Mathematics.  The PLDs can be downloaded by grade level, course, grade band, all high school courses, or as a complete package.  A PowerPoint presentation is also available to explain the structure of the PLDs.  The PLDs are rubrics indicating the broad categories that will be used to report learner performance on an assessment.  Five levels of command include 5: Distinguished, 4: Strong, 3: Moderate, 2: Partial Command, or Level 1 indicating a range from no work shown to Minimal command."

Technology Guidelines for PARCC Assessments (updated January 2015) "provides minimum and recommended specifications for computer hardware, input devices, and security requirements; and suggests recommended levels of bandwidth that will support schools instructional and assessment needs" (PARCC description).

video camera imageTeacher Chris Aviles (2015, February 3) posted an informative video at Tech & Learning that introduces teachers to their role in administering the PARCC online on test day: PARCC: Won't Somebody Please Think of the Teachers.


SBAC Assessments:

The Smarter Balanced Assessment Consortium (SBAC) assessments will include summative assessments for accountability purposes and optional interim assessments for instructional use and will use computer adaptive testing to the greatest extent possible.  Assessments will go beyond multiple-choice questions to include extended response and technology enhanced items, as well as performance tasks that allow students to demonstrate critical-thinking and problem-solving skills.  See SBAC Practice and Training Tests.

Read SBAC's Accessibility, and Accommodations that outline the kinds of testing supports and tools that will be made available to all students, and particularly those with disabilities and English-language learners for the Common Core assessments.

Maximize your opportunities to use technology in instruction.

Friendly reminder Gif

In Technology Readiness for College and Career Ready Teaching, Learning and Assessment, the State Educational Technology Directors Association (2012) reminded educators that:

"Digital testing requires digital learning. Students using technology to take high--stakes tests must have significant opportunities to develop and demonstrate master of tested knowledge, skills and abilities via substantially similar technology prior to being tested.  Teachers must be prepared to support this shift in instruction" (p. 1).

CT4ME has multiple resources to help with this endeavor.
