The following list highlights platforms verified by ESSA standards, university research, and widespread adoption by educators from 3rd grade through higher education.
An online learning platform focused on math and reading that provides 1:1 tutoring, personalized lessons and parent reporting. Before creating a curriculum, this K-12 resource performs a diagnostic check to identify gaps, then assigns a specialized tutor to guide the student through advanced topics while following US educational requirements.
2. Zearn Math
Top rated digital curriculum built on Eureka Math. It holds up ESSA Level 1 status because of its proven ability to address achievement gaps through a combination of digital lessons and small group learning.
3. ST Mathematics
Created by the MIND Research Institute, this visually oriented program uses spatiotemporal reasoning to teach math concepts without language barriers, making it ideal for ELL students and early learners.
4. IXL Mathematics
The industry standard for skill fluency. It provides “Real-Time Diagnostics” that gives educators an accurate snapshot of student proficiency across all state standards.
5. Desmos Classroom
In addition to its famous graphing calculator, Desmos offers free, high-quality digital activities that encourage students to model math and share their reasoning with the class in real time.
6. Khan Academy
A non-profit organization providing a massive library of standards-compliant videos and hands-on exercises. Its new AI tutor, Khanmigo, offers Socratic training to guide students through difficult proofs.
7. WolframAlpha
A calculator essential for higher education (grades 12-20). Provides step-by-step solutions for complex calculus, linear algebra, and differential equations.
8. Illustrative mathematics
A problem-based core curriculum designed to promote ‘learning by doing’. Focuses on constructing mathematical arguments and using precise academic language.
9. DeltaMath
Preferred by middle and high school teachers for its rigorous approach. It contains over 3000 types of problems with detailed step-by-step explanations for each missed answer.
10. Interactive PhET simulations
University of Colorado Boulder research-based simulations. They allow students to “play” with variables in equality, fractions, and area models to visually see the mathematical implications.
11. OpenStax
Rice University’s Center for Peer-Reviewed Open Source Textbooks. It is an essential resource for college-level courses, offering high-quality mathematics and statistics texts for free.
12. Mathigon / Polypades
Known as the “Math Playground,” it provides advanced virtual manipulatives that allow students to explore geometry and number theory through tactile number tiles.
13. GeoGebra
A cross-platform tool for geometry, algebra and 3D graphics. It is open source and maintained by a global community of mathematical researchers and educators.
14. Youcubed
Based at Stanford University, this site provides low-floor, high-ceiling tasks designed to encourage growth mindsets and deep conceptual thinking in mathematics.
15. The art of problem solving
The ultimate resource for advanced math students and competition preparation. It offers rigorous textbooks and interactive challenges for high-achieving learners.
