What is Synthesis Tutor?

Synthesis Tutor is a digital math tutor for children, designed for ages five to eleven. It teaches the standard K-5 syllabus, from counting and the four operations to fractions and early algebraic thinking, through interactive, game-like lessons with a spoken guide. Each lesson contains small checks of understanding, and a child advances once those show the material has been grasped; when an error appears, instruction is adjusted to address the gap. For children under seven all text and answer options are read aloud, and the voice speed can be changed. Parents receive progress reports. According to the company, AI is used where it fits while educators and neuroscientists design most of the teaching. The app runs on iPad, Android tablets and desktop computers including Chromebooks, and is offered in English and Spanish. It is published by Synthesis School, Inc.
