Primary school mathematics plays a crucial role in building foundational skills, and whether children develop fast and accurate computing abilities at this stage can significantly impact their future. Since mathematical proficiency relies heavily on practice, relying solely on a few school tests or exams won’t provide enough reinforcement. Additionally, grading homework can be time-consuming and labor-intensive for teachers and parents alike. As parents of primary school students, we developed this app to help children master key math concepts like addition, subtraction, multiplication, and division. Our app is tailored to meet the needs of young learners, offering customizable question sets. Children can draw and make notes during their practice sessions, and each test tracks their performance, including time taken and highest score achieved. This way, kids can challenge themselves, track their progress, and improve consistently
