Math Practice is designed to help your child practice what they have learned in our main app, Math age 3-5 - covering the same ten topics, but with all-new activities and graphics. Each topic features several fun games and activities, intended to consolidate learning through repetition and practice, followed by a quiz to test the child’s knowledge, and a certificate when they get all the questions right. Our math apps have been proven to be effective. An independent study by the University of Nottingham in the UK showed that 6 weeks of using the onebillion math app was as effective as 18 months of standard classroom practice. In fact, one week of using the onebillion software for 30 minutes a day equalled three months of formal education.
