Dear KooBits, thanks for your timely help and bravo to your team in creating such a fabulous way of facilitating the children in learning maths. My son learnt so much in practicing koobits… His teacher was amazed at his enthusiasm in understanding maths concept. Really a lifesaver to all maths loving kids Thanks again.”

I admit, I’m not really a fan of problem sums, however this portal has changed my mind about sums. I thought KooBits was just some random website. Boy was I wrong! :) This website has made me enjoy math. I enjoy my life here. Thanks a lot!”

Ezra Lim Zheng Xi, Pei Hwa Presbyterian Primary School

My classmates are going crazy about koobits. Those with iPads play koobits when the teacher is not in the classroom or when we are walking in school. They also play when we are queuing up for dismissal.”
