About

Synthesis Tutor is a web-based math learning program that works like a personal tutor for children aged 5 to 11. It addresses a common problem for families: keeping a child's math skills on track without constant parental supervision or expensive private tutoring. The Tutor adapts each lesson to the child's ability and gives immediate feedback.

The product is made by Synthesis, an education company whose origins trace back to a school program developed at SpaceX. Lessons cover the standard K-5 math curriculum — from counting and addition through fractions and algebraic thinking — presented through a multisensory, gamified interface rather than worksheets. The Tutor evaluates answers as the child works, identifies gaps in knowledge, and adjusts instruction accordingly, so each student progresses at their own pace. Parents can review progress reports while the child works independently.

Key Features

Adaptive instruction: The Tutor evaluates responses immediately and adjusts the difficulty and content to match each child's current level.
One-on-one tutoring experience: Children receive patient, tailored guidance on every problem, designed to feel like working with a real teacher.
Gap-filling lessons: When mistakes occur, customized instruction targets the specific knowledge gaps behind them to strengthen foundations.
Multisensory, hands-on activities: Lessons use manipulatives and interactive on-screen play to build understanding rather than rote memorization.
K-5 curriculum coverage: Topics include counting and cardinality, addition, subtraction, multiplication, division, fractions, and algebraic thinking.
Gamified progression: Children unlock levels and advance through an experience designed to keep them engaged and motivated.
Progress reports: Parents and teachers can monitor a child's development without needing to sit through each session.

Who It's For

Synthesis Tutor is aimed at parents of elementary-aged children (5-11) who want supplementary or primary math instruction at home. Homeschooling families use it as a core K-5 math curriculum, while other parents use it to reinforce classroom learning or fill gaps. Teachers and schools can also use it through the company's educator offerings. It suits families seeking an independent-learning tool that requires little day-to-day parental involvement, and children who respond well to visual, hands-on, and gamified instruction rather than worksheets.
