If your kids don’t read in their free time already, I’d use your parental authority to encourage them to start now. Being a voracious reader will help them on standardized tests, in high school, and in college once they get there. Also, it sounds like your older daughter is squared away in math, but make sure there aren’t any gaps. It’s critical to provide your kids with a solid education in algebra and geometry. If there are any issues, try to get a tutor sooner rather than later.
