The following list highlights fields certified by ESSA standards, university research, and widespread acceptance of teachers from grades 3 through higher education.
An online learning platform focused on math and reading that offers 1:1 tutoring, personalized lessons, and parent reporting. Before creating a curriculum, this K-12 resource uses a diagnostic check to identify gaps, then assigns a special teacher to take the student to advanced topics while following US education requirements.
2. Zearn Math
A highly rated digital curriculum built on Eureka Math. It’s catching up Section 1 of ESSA the state of its proven ability to close achievement gaps through a mix of digital courses and small group instruction.
3. Statistics of ST
Created by the MIND Research Institute, this first-of-its-kind visual program uses spatial and temporal reasoning to teach math concepts without language barriers, making it appropriate for ELL and early childhood students.
4. IXL calculations
Industry standard for skill fluency. It provides “Real-Time Diagnostics” that gives teachers an accurate snapshot of student performance at all state levels.
5. Desmos class
Beyond its popular graphing calculator, Desmos offers free, high-quality digital activities that encourage students to model math and share their thinking with the class in real time.
6. Khan Academy
A non-profit organization that provides a large library of standardized videos and exercises. Its new AI instructor, Khanmigo, offers Socratic training to guide students through difficult proofs.
7. WolframAlpha
The math engine is important for higher education (Grades 12-20). Provides step-by-step solutions for complex equations, linear algebra, and differential equations.
8. Illustrative Mathematics
A problem-based core curriculum designed to encourage “learning by doing.” Focuses on developing mathematical arguments and using precise academic language.
9. DeltaMath
It is preferred by middle school and high school teachers for its strong style. It includes over 3,000 problem types with detailed, step-by-step explanations for all the unanswered questions.
10. PhET Interactive Simulations
University of Colorado Boulder research-based simulation. This allows students to “play” with different equations, fractions, and spatial models to see mathematical results.
11. OpenStax
Rice University’s site for peer-reviewed, open-source publications. It is the premier resource for college-level courses, offering high-quality Calculus and math texts at no cost.
12. Mathigon / Polypad
Known as the “Math Playground,” it offers advanced manipulation that allows students to explore geometry and number theory through tactile digital tiles.
13. GeoGebra
A multi-platform tool for geometry, algebra, and 3D graphing. It is open source and supported by a global community of mathematics researchers and educators.
14. Youcubed
Based at Stanford University, this site offers “low-ceiling, high-ceiling” activities designed to encourage growth perspective and critical mathematical thinking.
15. The Art of Problem Solving
The ultimate resource for advanced math students and competitive preparation. It offers rigorous textbooks and interactive challenges for high-achieving students.
