Math Concept Map
Connect scattered math ideas like branches and see the next path to learn.
A project built directly by Ted TH Lee.
Why I built it
When you get stuck on a problem, the real gap is often not that problem but a missing concept sitting just before it. I wanted to see, at a glance, where you're stuck and what to step on next.
What it does
- A map connecting 135 math concepts from the 2022 curriculum by prerequisite order.
- Tap a concept for an explanation and jump straight into related past exam questions.
- Tracks wrong answers and revisits them with review quizzes.
- Saves your solving history and progress.
- Ported to an iOS app alongside the web, so it works offline too.
Who it's for
Students and parents who want to find where the gaps are in math
How it was built
Workbooks rarely show the links before and after a concept. This map connects 135 math concepts from Korea's 2022 revised curriculum by prerequisite order, beginning with the need to find an earlier missing idea when a problem becomes stuck.
Checking those links meant reading curriculum documents more than writing code. The result is not only a reference map: a learner can move from a concept explanation to related past questions, then carry wrong answers and progress into review.
How you use it
Find a concept's place
Use the map to see the concept being learned and the ideas connected before and after it.
Read and solve
Select a concept to open its explanation and solve related past exam questions.
Return for review
Solving history and wrong answers are saved, so review quizzes can pick up the same learning path.
