We observe that there are many students are unclear and dislike math. Some students in primary school want to have extra class like the higher grade. Most of the students forget their lesson when they are not practicing their lesson. To solve the problem above, T.I.E team created an app that called StuLab. This app is an app that help students in grade one to six learn and practice math. In each grade there are three level, easy; medium; hard. In each level there are nine video lesson and 15 practices.
