This document summarizes a seminar on using mobile apps to teach mathematics at the primary level. It describes grouping students into levels based on their math skills and exposing them to interactive apps on a mobile phone to help them learn counting, number recognition, and the four basic operations. The approach uses a trial and error method with immediate feedback to help slow learners. Observations found this approach helped students learn at their own pace and engaged them in learning. The conclusion is that interactive technology can make learning fun and help students learn skills like number sense that prepare them for further education.
