Common Core Math Worksheets

Common Core math worksheets are practice pages that match the Common Core State Standards for mathematics, the shared learning goals used or adapted by many US states from kindergarten to 12th grade. This page maps our free printable worksheets to each grade and domain from kindergarten to 8th grade, so you can find practice for the exact standard a child is working on. Every worksheet is a PDF with an answer key.

Quick answer: Common Core math worksheets practice the skills named in the Common Core standards, which are grouped by grade into domains such as Operations and Algebraic Thinking (OA), Number and Operations in Base Ten (NBT), Fractions (NF), Measurement and Data (MD), Geometry (G), Ratios (RP), the Number System (NS) and Expressions and Equations (EE). The table below links to free PDFs with answer keys for each grade from K to 8. Updated October 2026.

Common Core math worksheets by grade and domain

This table matches each of our worksheet topics to the Common Core domain it practices most closely, with the number of free PDFs in brackets. A topic can serve more than one standard, so use it as a guide and check your own state or district standards for the exact order.

How to read a Common Core math standard

Each standard has a code that tells you the grade, the domain, the cluster and the number. For example, 3.OA.C.7 is grade 3, domain OA, cluster C, standard 7. The official wording is on the Common Core State Standards for Mathematics site. Here are five codes explained:

Common Core math domains from kindergarten to 8th grade

The standards group math into domains. Some run across many grades, such as Geometry, and some begin later, such as Ratios in grade 6 and Functions in grade 8:

Common Core math worksheets and Common Core math practice at home

Common Core math is often described as a way of teaching, but the standards are a list of what students should be able to do at each grade. Parents who want Common Core math practice at home can start from the grade table above: choose the domain the class is on, print one Common Core worksheet, and use the answer key to check it together. The same page works as a Common Core math worksheets PDF library, since every file is a free PDF for US Letter or A4.

A few habits help. Ask the child to explain how they got an answer, since many standards ask for explanation as well as the right number. Try a second method, such as an array or a number line, and compare. Many states use their own standards, based on or similar to Common Core, so treat the grade tables here as a guide and check the order your school uses.

Common core worksheets by grade: where to start

If you are not sure where to begin with Common Core math worksheets, start one grade below the one your child is in and move up. A short run of common core worksheets that feels easy confirms the basics, while a run that feels hard shows which domain needs work. The grade pages have the full lists: use the kindergarten and early grade pages for counting and addition, the upper elementary pages for multiplication and fractions, and the 6th to 8th grade pages for ratios and equations. Each page shows the number of Common Core math worksheets and their answer keys.
