MathsightAbout Mathsight
Mathsight is a set of 159 short animated maths lessons for children in Grades 1–6, ages 6–12. Each lesson takes one mathematical idea, explains it in about two to three minutes of English narration, and ends with a printable worksheet so that watching turns into doing. The whole course is delivered as an iOS app; this website publishes every transcript, every worksheet and a preview of every lesson for free.
Why it is built this way
Most elementary maths videos try to fit a whole chapter into ten minutes, and a child loses the thread halfway through. Mathsight goes the other way: one lesson, one idea. If a topic needs two ideas, it becomes two lessons.
Three rules have held since the first lesson:
- One idea per lesson. Nothing is introduced that the lesson does not use.
- The narration is the teaching. The voice explains; the animation shows what the voice is describing, at the same moment. No talking head, no music competing with the words.
- Every lesson ends in pencil on paper. A one-page worksheet follows each lesson, and each grade has a workbook that collects them.
What is on this site for free
- A 15-second preview of all 159 lessons.
- The full transcript of every lesson, as plain text on the lesson page.
- Every worksheet PDF, plus six complete workbooks — one per grade.
- Twelve complete lessons in full, so you can judge the teaching style before installing anything.
No account is needed to use any of it.

How a lesson is made
Every lesson is scripted first, then drawn as an animation built from geometric primitives — counting objects, number lines, arrays, place-value blocks, fraction bars, angle diagrams. Words and drawings are timed against the same script, so the picture never runs ahead of the explanation. The worksheet is written from the same script, question by question, so nothing is practised that was not taught.
Who makes it
Mathsight is published by Guangzhou Pashanhu Intelligent Information Co., Ltd., an independent software company based in Guangzhou, China. The lessons, worksheets and the iOS app are made by the same small team.
