Kids need some unscheduled time. Find her a couple of friends so that they can hang around together. Let her read books that you usually do not let her. You can rely on r Avigdor Miller who says to read classics if you must to read in English … parental mental health would be a good justification.
If she is at least 12, she can work or volunteer at a day camp, this would be a great experience. None of our daughters regretted this.
