What modifications for learners who are exceptional do you see?

While I was doing my field work there was one student in the classroom that I noticed was always doing something different than the rest of the class. I inquired the teacher about this and found out that she was a little below grade level in the subject that was being worked on during the time I was there. So, for that amount of time, while the other kids did vocabulary sheets for english time, she would write stories and bring them to the teacher and would go through them to make sure all of the words were spelled correctly. This helped her to be working on the same subject as the rest of the class, but also in a way that was more on her level and enjoyable for the student too. I think that is something that could be a good idea that if one student specifically is struggling, then if there is a way to adapt the way she learns, like just working on writing and spelling rather than doing the reading and vocabulary sheets all of the time, then that is something that would be good for any teacher to try out.
