Kotokan teaches strategies to analyze, break-down and visualize information in problems. Through practice children may solve problems of increasing complexity.
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.
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.
Content browse and filtering
You can find lots of problems, grouped in what we call challenges. They are organized by curricular tags and also by problem-solving strategies.
Explanations to guide them
Some challenges have short pedagogical lessons to remind your students key contents. You’ll soon be able to edit and add your own explanations.
Assign content with due dates
When you assign a challenge you can set start and due dates to make your students focus on specific contents.
Follow up at a glance
You’ll see how all the students are performing in each challenge, if they’ve done the problems or they are missing.
Different types of questions
Numerical, short-text, single or multiple-choice and open-ended questions will allow you to validate if a student can solve and really understands.
Rate open-ended questions
You can rate from 0 to 10 the problems that require your students to explain a solution. You cando it fast or you can take time to review carefully.
