Dhātu
Nurturing Deep Conceptual Understanding of Math
Imagine a learning system where math feels supportive, not threatening — where mistakes are met with guidance, not judgment. Such an approach can transform the experience, building clarity, logical reasoning, and confidence in every student.
Dhātu
Nurturing Deep Conceptual Understanding of Math
Dhātu is a technology-enabled mathematics learning platform designed to enhance mathematical learning and problem-solving skills in students.
Built on the Root Question Framework, conceptualised by Prof. Jeffrey D Ullman, Professor Emeritus at Stanford University and Turing Award winner, features comprehensive mathematics content made available to schools, students and teachers across the country at no cost.
Prayoga’s team of researchers and educators have crafted mathematics questions that address key concepts, defining every step and process needed to arrive at solutions.
Anticipating common errors in the process, Dhātu provides tailored hints for every possibility, guiding students through their learning journey.
Comprehensive Question Bank for grades 9 to 12 with practical applications
Levels with progressive difficulty to support preparations for JEE, Olympiads and advanced exams.
Non-threatening, guiding students to learn from mistakes and engage in self-assessment for continuous improvement.
Customizable assignments, instant feedback and track performance of students.
