Teach them problem-solving strategies

Kotokan teaches strategies to analyze, break-down and visualize information in problems. Through practice children may solve problems of increasing complexity.

For teachers, by teachers

Kotokan is a platform created for teachers. Our contents are developed by teachers and experts. We are willing to build a community of teachers to fulfil our mission.


Purposeful maths

The moment most children disengage from Maths is when it becomes abstract and they don’t understand “What it’s for”, or how it connects to their own life. We use storytelling and content customisation to keep children engaged.
