MobyMax
Adaptive K–8 practice and curriculum in math, reading, language, writing, science and social studies that starts with a placement test and automatically fills skill gaps. Widely used in schools; families can subscribe starting at $7.99 a month after a 30-day free trial.
What is MobyMax?
MobyMax is an adaptive learning platform for kindergarten through 8th grade. It is best known in schools, where teachers use it to find and fix the specific skills each student is missing. Families can subscribe too, starting at $7.99 a month as of October 2026.
The core idea is gap-filling. A placement test finds what your child does not know yet, and the program builds lessons to close those gaps without you assigning anything.
How it works
Your child takes an adaptive placement test in each subject. MobyMax then starts them on the first missing skill and moves forward as they show mastery. Grade-level benchmarkers and skill diagnostics check progress along the way.
Kids earn badges, certificates and short game breaks as rewards. Parents can let the system choose lessons or assign specific ones, and customizable reports show progress by skill. Homeschool parents usually set up a teacher account and add each child as a student. Short daily practice blocks fit well alongside a main curriculum.
What it covers
| Subject | Scope |
|---|---|
| Math | Early number sense through algebra readiness |
| Early reading and reading | Phonics, fluency, comprehension |
| Language and writing | Grammar, vocabulary, sentence and paragraph writing |
| Science and social studies | K–8 content aligned to NGSS and state standards |
MobyMax says it has more than 60 curriculum, assessment and practice modules, aligned to Common Core, NGSS and state standards.
Who it's best for
MobyMax suits families who need to catch a child up after a move, an illness or a switch to homeschooling, and parents who want adaptive practice across many subjects for a low price. It is also handy for kids working above grade level in one subject and below in another.
Look elsewhere if your child needs a polished, game-rich app to stay motivated, or if you want a complete teacher-led curriculum. Families who want a full online program often choose Time4Learning instead.
Pricing at a glance
The family plan starts at $7.99 a month after a 30-day free trial. Teachers can register for a free version, and school licenses are quoted. MobyMax does not publish detailed family plan terms, so confirm the price and renewal before you subscribe.
Can a scholarship or ESA pay for it?
Possibly. Some education savings account programs allow educational software and curriculum, while others only reimburse purchases or limit spending to set vendors. Each program decides.
