Zearn is a nonprofit online math program that gives students in kindergarten through eighth grade daily digital lessons designed to reinforce what they learn in class. Zearn Math is used alongside a teacher’s regular math instruction rather than replacing it, and it is free for individual classrooms with up to 35 students. The program was founded in 2012 and is based in New York City, and it now reaches roughly one in four elementary school students in the United States along with more than a million middle schoolers.
What Is Zearn Math?
Zearn Math is a K-8 digital curriculum built around independent practice, video instruction, and hands-on visual tools. Students work through more than 1,000 digital lessons organized into units called Missions, each aligned to grade-level math concepts. A typical session starts with a short fluency warm-up, followed by an interactive lesson where students watch brief videos, use digital manipulatives, and solve problems with instant feedback.
The program was created by Zearn, a 501(c)(3) nonprofit founded by Shalinee Sharma and Evan Rudall. It runs entirely in a web browser on Chrome, Safari, Edge, or Firefox, and it does not require a separate app or software download.
How Does Zearn Math Work in the Classroom?
Teachers assign a Mission that matches the concept they are currently teaching, and students then move through a sequence of lessons at their own pace. When a student answers incorrectly, Zearn automatically provides scaffolded support, such as a shorter video or a simpler version of the problem, instead of just marking the answer wrong.
Teachers get real-time data showing which students are struggling and on which specific skills, which lets them intervene quickly during class instead of waiting for a test. Many schools use Zearn during a dedicated math block, often called “Zearn time,” where students rotate between digital lessons, small-group instruction with the teacher, and paper-based practice.
Is Zearn Math Free?
Yes, Zearn Math is free for individual teachers and classrooms of up to 35 students, giving full access to the digital lessons and instructional materials. Paid School and District Accounts exist for schools that want implementation support, professional development, and administrative tools across multiple classrooms. Several states, including Ohio, South Carolina, Colorado, and Virginia, have funded free district-wide access to Zearn as part of statewide math acceleration efforts.
What Grades and Subjects Does Zearn Cover?
Zearn Math covers kindergarten through eighth grade, with the core interactive digital platform built primarily for K-5 students. Some middle school teachers use the K-5 lessons to help students fill gaps in foundational skills before moving into grade-level middle school content. The curriculum focuses exclusively on mathematics and does not offer lessons in reading, science, or other subjects.
Does Zearn Math Actually Improve Math Scores?
Zearn Math has received a “Strong” rating from Evidence for ESSA, the highest tier awarded by that independent research clearinghouse for education programs. In Ohio, a quasi-experimental study conducted with the state’s Department of Education and Workforce found that consistent Zearn use was linked to significantly higher math proficiency rates, with the largest gains among students who completed three or more grade-level lessons per week.
These results align with the program’s design, which emphasizes mastery of a smaller number of core concepts rather than surface-level coverage of many topics. The Institute of Education Sciences has also funded independent efficacy research on Zearn Math, reflecting its use as a program with a documented research base rather than an unproven tool.
How Do Parents Use Zearn Math at Home?
Parents can create a free account to let their child continue Zearn Math lessons outside of school, which is useful for extra practice or during school breaks. Because the platform gives instant feedback and adapts support when a student struggles, children can often work through lessons with minimal help from an adult once they understand the basic routine.
Parents who want to support their child’s progress can check the “Tower of Power,” a running fluency tracker within the platform, and talk with their child’s teacher about which Mission the class is currently working through. Zearn also offers select Spanish-translated digital lessons for grades K-5, which helps bilingual families support learning at home.
Conclusion
Zearn Math has become one of the most widely used digital math supplements in U.S. classrooms because it pairs free access with a research-backed instructional model. For parents, teachers, and students trying to understand what the program actually does, the short answer is straightforward: it delivers daily, grade-level digital math lessons that reinforce classroom teaching, adapt to each student’s needs, and give teachers real-time insight into where support is needed most.
FAQs
What is Zearn Math used for?
Zearn Math is used to reinforce daily classroom math instruction through independent digital lessons. Teachers assign lessons that match what they are teaching, and students practice those skills with video support, digital manipulatives, and instant feedback, building fluency and conceptual understanding alongside regular classroom teaching.
Is Zearn Math free for teachers?
Yes. Individual teachers can create a free classroom account supporting up to 35 students and one teacher, with full access to the digital lessons and instructional materials. Schools and districts that want additional support, training, and administrative features can purchase paid School or District Accounts.
What grade levels does Zearn Math support?
Zearn Math’s core digital lesson library is built for kindergarten through fifth grade, with additional materials extending coverage through eighth grade. Some middle school teachers also use the K-5 lessons to help students strengthen foundational skills before tackling grade-level middle school content.
Does Zearn Math replace a teacher or textbook?
No. Zearn Math is designed as a supplement to a teacher’s existing math curriculum, not a replacement for classroom instruction. It reinforces what students are learning in class through independent digital practice, while teachers continue to lead direct instruction and small-group support.
Is there a Zearn Math app?
No, Zearn Math does not have a dedicated mobile app. The platform runs entirely through a web browser, including Chrome, Safari, Edge, and Firefox, so students access lessons by logging into the website on a computer, laptop, or tablet with internet access.
