What it is

Synthesis Tutor is a personalized math learning product for children ages 5–11, covering standard K–5 topics such as counting, arithmetic, fractions and algebraic thinking. Lessons target gaps in a child’s knowledge and use real-time micro-assessments to check understanding before advancing. For children under 7, text and answer choices are read aloud automatically, and voice speed can be adjusted. The Tutor is available in English and Spanish on the web and iOS, with other languages in progress. Schools, classrooms, homeschooling pods and districts can inquire through an interest form. A seven-day trial is listed, though the facts do not specify a free plan. Individual Monthly costs $35 a month for one child; Family Monthly is $29 a month for up to seven children. Annual and lifetime options are also listed, including Family Annual at $119 a year for up to seven children.
