Creating a math app like Prodigy requires merging education with fun. The app should target a specific age group and curriculum, offering a range of math topics and difficulty levels. Like Prodigy, you can incorporate game mechanics like challenges, characters, and rewards to keep students engaged. The key is to make the problems relevant to the chosen age group and their interests. Don't forget to include an adaptive learning feature that adjusts to the student's strengths and weaknesses, ensuring they're neither bored nor overwhelmed. Finally, consider adding progress tracking and helpful feedback to keep students motivated and on track for math mastery.
