ST Math
ST Math is a visual, puzzle‑based online math program from the nonprofit MIND Research Institute that teaches concepts before symbols through the adventures of a little penguin named JiJi.  Instead of multiple‑choice questions, students solve animated challenges that require them to experiment and notice patterns, building deep conceptual understanding from K–8. Parents like that there’s minimal text, which makes it accessible to English‑language learners and dyslexic students, and that kids can work at their own pace. While it’s designed as a supplemental school program, homeschool subscriptions and some school partnerships make it available to families as well. Pricing for home use is comparable to other premium math apps, and many families feel the brain‑based design delivers strong value.
