Startup Idea: Educational Summer Workbook Software for School Children

Startup idea to develop a software that serves as an equivalent to physical summer workbooks for students. The software will cover basic subjects like Math and English, designed to keep children engaged while not overwhelming them. In addition, it should also feature a tracking system, monitoring the learning progress of each child throughout summer. The software should be scalable and designed to fit every grade level - elementary to middle school.

I am a work in it tech. I new kind of software program that I would be interested in would be software for school. I am looking for something similr to the workbooks that you use in the summer to keep the kids engaged daily like the teacher owuld do in class during the year. It would cover math and spelling basics. There are a lot of programs but none I have come across that are as good as the workbook maht and english are. I would want it to help keep them on track in the summertime so that they are learning a little but not being overwelmed.
The best solution would be to come up with something similar to the workbooks they sell in the store but as a software program. A tracker so I can keeptrack of their summerlearning progress would also be very helpful as well. If it could be made to work with elementary school then one for middle school so it works with each grade level that would be great as well. I have tried some programs but they dont seem to teach them much.
