Hi Danyelle,
Great idea! I completely agree that this is an area we need to focus on in education. One factor that I, myself, struggle with when trying to improve my financial literacy is the dryness of the content. To facilitate continued user engagement I'd think about ways to make it accessible to high school kids. Are there ways to gamify the learning experience? Can they access through a gaming console like Xbox or PlayStation? Can we surface the content through a subject they're already interested in - like a sports or a film example? For ex: when setting up the app you choose from a variety of themes and then your lessons are provided in the context of that subject, using real-world examples. This can bring a sense of storytelling to the experience to keep users interested and coming back.
