ST Math helps students learn math skills by teaching concepts visually before introducing numbers or symbols, so learners build genuine understanding instead of memorizing steps. Created by the nonprofit MIND Research Institute, this PreK-8 program uses animated puzzles that require students to solve problems through spatial reasoning, then connects that reasoning to traditional math notation. The result is a learning approach that reaches students regardless of reading level or native language, since the earliest puzzles use no words at all.
What Is ST Math?
ST Math, short for Spatial-Temporal Math, is a supplemental instructional software program for students in PreK through eighth grade. It was created by the MIND Research Institute, a nonprofit organization, and is game based instructional software for K–12 students that can be integrated into classroom instruction, used in a computer lab, or accessed at home.
Three University of California researchers developed the underlying idea in the early 1990s, aiming to teach math the way children naturally learn it, through visual and hands-on experience. In 1998, they formed an independent nonprofit, now known as MIND Research Institute, to build out the concept into software. That research foundation still shapes every puzzle in the program today.
How Does ST Math Teach Math Concepts Visually?
ST Math teaches math concepts by presenting them as picture-based puzzles before any symbols or equations appear. Students build mastery by engaging with visual puzzles before being introduced to symbols or equations, testing ideas, receiving immediate feedback, and developing the mindset of a mathematical thinker.
Interactive animated visual manipulatives provide informative feedback to student solutions, which lets students see immediately whether their thinking was correct. This informative feedback loop is central to the design: instead of simply marking an answer right or wrong, the software shows students the consequence of their choice, so they can adjust their reasoning and try again.
What Role Does JiJi the Penguin Play in ST Math?
JiJi is the animated penguin character that guides students through every ST Math puzzle. Students help JiJi pass obstacles by solving spatial math puzzles, and this game-based structure motivates learners to keep working through increasingly complex problems.
Because JiJi’s journey depends on a correct solution, students get a built-in reason to persevere through challenging puzzles rather than guessing. Many parents and teachers report that this character-driven format keeps students engaged with math for longer stretches than a standard worksheet, which supports the repeated practice needed for skill mastery.
Does ST Math Improve Student Math Proficiency?
Independent research indicates that ST Math is associated with measurable gains in student proficiency. A WestEd evaluation of 209 second through fifth grade classrooms using ST Math at 129 California schools found that grades using the program for one year showed 6.3 percent more students scoring proficient or better on the California Standards Test, compared to similar schools not using the program.
That kind of third-party evaluation matters because it isolates the effect of the program itself rather than relying on self-reported results. Schools considering ST Math can review these independent studies to understand how the approach performs across different grade levels and student populations before adopting it district wide.
How Is ST Math Used in the Classroom and at Home?
Teachers typically use ST Math as a supplement to core math instruction, assigning specific objectives to individual students, small groups, or an entire class. The program includes an assignments feature that lets teachers assign any ST Math objective to individual students, groups, or the whole class outside of their regular journey, along with progress reports that show minutes played and puzzles completed.
Because ST Math is integrated into classroom instruction but can also be used in a computer lab or at home, families can extend practice beyond the school day. Many schools recommend a consistent daily or weekly time block, since steady use over the school year is what drives the proficiency gains documented in independent evaluations.
Who Can Use ST Math?
ST Math is designed for PreK through eighth grade students and works across a wide range of learning styles and language backgrounds. MIND, the nonprofit behind the program, reports impacting millions of students across all 50 states.
MIND Education has partnered with schools and districts for over 25 years to help every learner build true conceptual understanding in math, regardless of background or learning style. Because the earliest puzzles rely on visuals rather than text, the program is also commonly used with English language learners and students who benefit from a non-verbal introduction to new concepts.
Conclusion
ST Math helps students build real math understanding by starting with visual puzzles instead of abstract symbols, giving learners a chance to reason through problems before they ever see an equation. Backed by decades of research from the MIND Research Institute and independent evaluations showing measurable proficiency gains, the program offers a structured, evidence-based way to strengthen math skills both in the classroom and at home. Educators and parents exploring supplemental math tools can review MIND Research Institute’s published studies or ST Math’s official program page to see how it might fit their students’ needs.
Frequently Asked Questions
What grade levels does ST Math cover?
ST Math is built for students in PreK through eighth grade. The puzzles increase in difficulty as students progress, moving from purely visual problems in early grades toward puzzles that connect directly to symbolic math notation in later grades.
Who created ST Math?
ST Math was created by the MIND Research Institute, a nonprofit organization founded by University of California researchers in the late 1990s. The organization continues to develop the program using ongoing research in neuroscience and education.
Is ST Math a full curriculum or a supplement?
ST Math is a supplemental program, meaning it works alongside a school’s existing core math curriculum rather than replacing it. Teachers typically assign ST Math puzzles to reinforce concepts taught during regular classroom instruction.
Can students use ST Math at home?
Yes, students can access ST Math outside of school on a computer or supported tablet. Many teachers encourage regular home practice, since consistent use over time is linked to stronger proficiency gains.
Does research support ST Math’s effectiveness?
Yes, independent evaluations have studied ST Math’s impact on student proficiency. A WestEd study of California schools found meaningfully higher proficiency rates among students who used the program for a full school year compared to peers who did not.
