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!”

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.”
