Many states across the country have math standards based on the Common Core Math Standards. As such, educators need teaching and learning resources that pair with the goals of the standards. The good news is that CT4ME is a prime source from which to select resources.
Notes and General Resources
Strands: Each cluster below provides general resources for it and then domain specific resources. Each domain includes technology investigations, multiple choice and constructed response exercises, and performance tasks. Students should be able to review on their own using the resources.
The standards for mathematical practice, as they apply, are noted within many of those resources.
There are eight standards for mathematical practice within the Common Core State Standards (CCSS) for Mathematics (2010):
Some files in our collection are in pdf format. If needed, download Adobe Acrobat Reader, free software for viewing and printing PDF files.
To interact with virtual manipulatives included within the Wolfram Demonstrations Project: Download the free Wolfram player.
You might need to download Java, a free plugin to interact with virtual manipulative applets.
Note: See Java's Help information on how to enable Java in your web browser, if an applet does not run after an installation.
Note: Resources also include links to online videos. CT4ME has reviewed those for suitability and appropriateness for classroom use. If you are concerned about students using YouTube videos where they are found, ViewPure.com provides a "Purify" button to add to your "favorites" toolbar that will simplify YouTube videos by removing the ads and comments that might come with your selectionyou see only the video simply by clicking on the button.
Note: Newer versions of virtual manipulatives are written in HTML5.
Within our collection of resources are interactives from NCTM Illuminations. Illuminations indicates that some of those run on older software, such as Flash* and Java. If you access an interactive and the activity is not visible, see https://illuminations.nctm.org/troubleshooting/ for possible solutions to use the activity.
*Note: Flash Player is at end of life, per Adobe's December 2020 announcement. "Since Adobe will no longer be supporting Flash Player after December 31, 2020 and Adobe will block Flash content from running in Flash Player beginning January 12, 2021, Adobe strongly recommends all users immediately uninstall Flash Player to help protect their systems." See Best Flash Player Alternatives To Use In 2023 For Playing FlashBased Multimedia Content posted at WeTheGeek, which provides information on eight free or paid alternatives.

Lack of understanding in math may be due to lack of understanding of the vocabulary. 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 nonexamples of the word, and characteristics and facts about the word, such as would be found using the Frayer Model. The Wisconsin Department of Public Instruction includes a downloadable form for the Frayer Model that students can use.

In addition to math vocabulary, students should also know key vocabulary found on standardized tests. Marileee Sprenger (2021) created "a list of 25 essential highfrequency words that are used in standardized assessments and other academic contexts across states and grade levels." They Include: "analyze, cite, compare, contrast, demonstrate, describe, details, determine, develop, distinguish, evaluate, evidence, explain, infer, interpret, main idea, paraphrase, persuade, point of view, relevant, structure, summarize, support, theme, and trace" (Introduction section). Such words are not typical of everyday speech.
Vocabulary 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 (K8 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:

Virginia Department of Education Mathematics Vocabulary Word Wall Cards for grades K8, algebra 1, geometry, algebra 2; and algebra, functions and data analysis. The "Mathematics vocabulary word wall cards provide a display of mathematics content words and associated visual cues to assist in vocabulary development." The Virginia Department of Education also indicated that the "cards should be used as an instructional tool for teachers and then as a reference for all students, particularly English learners and students with disabilities."
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 3High 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 beginningofyear 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 K8 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 threeyear 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.

Note: Membership in the PARCC and SBAC consortia has decreased since 2010. Many states are working to develop their own summative assessments. New Meridian assists states in this endeavor.
PARCC
New Meridian took over management of PARCC's testing business in 2017. Find released test items among its resources. See: PARCC Agent Rolling Out Pool of Items for Custom State Assessments by Dian Schaffhauser, December 6, 2018.
Under its resource for Math Test Design, New Meridian includes test specifications, performancelevel descriptors, evidence statements including calculator designations, and a Mathematics High Level Blueprint that "defines the total number of tasks and/or items for any given grade/course assessment, the item types, and the point values for each. These are intended to help the "general public better understand the design of the state summative assessments." New Meridian also includes a section on accessibility and how it is incorporating universal design and accessibility features and accommodations into assessments.
The Smarter Balanced Assessment Consortium (SBAC) includes summative assessments for accountability purposes and optional interim assessments for instructional use and will use computer adaptive testing to the greatest extent possible. Assessments go beyond multiple choice questions to include extended response and technology enhanced items, as well as performance tasks that allow students to demonstrate criticalthinking and problemsolving skills. See SBAC Practice Tests and Sample Questions.
Read about SBAC's Accessibility Resources and Accommodations that outline the kinds of testing supports and tools that are made available to all students, and particularly those with disabilities and Englishlanguage learners.

Maximize your opportunities to use technology in instruction.
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 highstakes 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).
