How it works

Measure. Adapt. Track.

Step 01

Measure

A 5-minute assessment finds each child’s actual skill level, not grade level. Real understanding.

Step 02

Teach & Adapt

Daily sessions teach concepts with guided examples, then adapt difficulty in real time. Children advance when ready, not by age.

Step 03

Track

Mastery is verified through spaced repetition, not one right answer. Skills are revisited over days and weeks to confirm lasting understanding.

Multiple children, one system

Three kids. Three levels. One dashboard.

Your youngest

Letter sounds, counting & five senses

Three subjects, one platform

Everything your homeschool needs

A complete reading curriculum, adaptive math, and hands-on science — all under one roof, all tracked by one system, all in one weekly report.

Math: Lessons + Adaptive Practice

Every concept taught · Pre-K through 8th grade

Every math concept has a structured lesson that teaches it — with read-aloud stories, guided examples, and hands-on activities. After each lesson, the adaptive engine takes over, giving your child practice at exactly their level and verifying mastery through spaced repetition. The lesson teaches. The engine makes it stick.

Lessons: Story-driven lessons for every skill, K through 8th

Practice: Adaptive engine adjusts difficulty in real time

Flow: Learn the concept → Practice until mastery

🔬

Hands-on Science

K through 8th grade · At-home experiments

Structured lessons across physical science, life science, and earth and space science. Every lesson includes a companion experiment guide so your child gets hands-on with the concepts they are learning — not just reading about them.

Physical: Forces, energy, matter & waves

Life: Cells, ecosystems, body systems & genetics

Earth: Weather, rocks, space & climate

Questions & answers

Lumastery covers math, reading, and science from Pre-K (ages 3-4) through 8th grade. Even your youngest can start with counting, letters, and observing the world at their level. The system places each child by demonstrated skill level, not by age or grade. A younger child working above their grade moves forward. An older child with gaps gets the support they need. Every child starts where they actually are.

About 15–20 minutes total, depending on how many subjects you cover that day. Each subject is a short, focused session — long enough to make real progress, short enough to hold their attention. Younger children get fewer questions with larger visuals and tap-to-answer exercises. Sit with them — you will see what they are learning, watch them work through problems, and be there when something clicks.

Each child takes their own placement assessment and follows their own adaptive path in math, reading, and science. Your kindergartner works on counting, blending letter sounds into real words, and observing living things while your fifth grader works on fractions, reading comprehension, and atoms. From one dashboard you can see where each child stands academically: what skills they have mastered, where they need extra support, and what is coming next. No switching between apps or tracking spreadsheets.

For math, Lumastery is the complete curriculum — and it works on two levels. Every math concept has a structured lesson that teaches it with read-aloud stories and guided examples. After each lesson, the adaptive engine gives your child practice at exactly their level, adjusting difficulty in real time and verifying mastery through spaced repetition. A placement test finds where your child actually is, and the system starts their lessons there — not at the beginning. You do not need a separate math textbook or lesson plan. For reading, Lumastery is also the complete curriculum — and it works on two levels. Learn to Read is a structured 157-lesson program across three levels that takes your child from first letter sounds through phonics, blends, digraphs, vowel teams, multi-syllable fluency, and all the way to reading real chapter books independently. You do not need a separate phonics program. On top of that, adaptive reading practice uses the same engine as math to give your child ongoing vocabulary, comprehension, and literary analysis exercises at exactly their level — adjusting difficulty and verifying mastery across sessions. The lessons teach. The adaptive engine makes it stick. For science, Lumastery covers physical science, life science, and earth and space science from K through 8th grade. Every lesson comes with a companion at-home experiment guide so your child can get hands-on with the concepts they are learning.

Be with your child. Sit next to them, watch them work, and encourage them when they get stuck. The system teaches the concepts, adjusts the difficulty, and tracks mastery — you do not need to plan lessons or figure out what comes next. Your job is the part that matters most: being present. When your child looks up after getting three in a row and grins, you are right there. The weekly report fills you in on the bigger picture so you always know where they stand.

It starts with a placement test that finds your child’s actual level in about 5 minutes. From there, structured lessons teach each concept with stories and guided examples. After each lesson, the adaptive engine gives practice problems at exactly the right difficulty. The engine uses spaced repetition — the same evidence-based technique behind the most effective learning tools in the world — to make sure skills stick long after they are first learned. Each child progresses through a prerequisite skill graph: they must demonstrate mastery of foundational concepts before advancing. When they struggle, the system lowers difficulty. When they show consistent accuracy across multiple sessions, they move forward. The result is a path that adapts to what your child actually knows, not what their age suggests they should know.

Every week you receive a personalized report for each child covering skills practiced, skills mastered, strength and weakness patterns, accuracy trends, what the system is adjusting next, and suggested home activities. You open the report and you know exactly where your child stands. No interpretation required.

Start with one lesson. Sit with them.

Sign up, add your child, and do the first lesson together. You'll see exactly what they know and what they're ready for. Free forever for one child. No credit card required.
