Piverb is an IIT-IIM alumnus venture. We offer an online non-routine Math course for classes 6, 7, 8 and 9. The course will run parallel to the school curriculum but with a higher emphasis on building intuition. The course focuses on teaching ideas from basics and creating a framework for students to 'figure out' and 'discover' new ideas. We emphasize a lot on the underlying idea behind every theorem and worry less about the mechanics of solving.
