You've got partial information. For example, the "85" figure is a maximum number of football scholarships for very large D1 schools and there are spectator attendance requirements and many other constraints. Some of those include a balance with women's sports, giving equal opportunity to women.
I don't know where you got the idea that D1 schools only give for football and basketball. It's not true. That said, full ride scholarships are exceedingly rare. Only about 2% of college athletes get them, and few of those go on to professional sports.
You could read up on NCAA regulations, but it's really moot because your kids aren't into sports. Although they are young and that can change, you never EVER bank on a sports scholarship! (Too much competition, too many issues with possible injuries and so on.)
My son went to a Division 1 school but not a sports powerhouse and not a big university. He got an amazing financial aid package combining a wide range of loans, scholarships and grants, both federal and college-based. The university he chose had tons of scholarships available for all kinds of programs, including the arts. The financial aid office was incredibly helpful, as was the cross country and track coach, in cutting through the maze of regulations and red tape. But he did not get an "athletic scholarship" by any means, and the coach was interested in him because he was a leader, a solid (but not Olympic level) runner, and because he had a great balance of activities.
In addition, most high schools give out a ton of scholarships, and so do many community organizations (civic groups, clubs, business groups, churches & synagogues, and more). They're small, but $500 here and $1000 there really add up!
You will also fill out, when the time comes, the FAFSA application for federal student aid. That takes into account your income, the number of children you have, and a bunch of other factors.
You should set up an education account through your state - the school will have info, and so will your tax preparer. Our high school had regular parent programs from the time the kids were in 9th or 10th grade, but they are open to the public so I would think you could go to them anytime, understanding that the particulars can and will change. But most states have programs where you can put money away to be used for education later, and not pay taxes on it.
Please understand that virtually no one can afford college anymore! Therefore, everyone is taking advantage of a variety of programs. There's a new proposal to make community college free for the first 2 years - after that, students are qualified/certified for many careers, or they can transfer to another university for the last 2 years.
My advice to you is to relax. Nurture your children and their interests based on who they are and what they enjoy. Encourage them to be well-rounded. Don't hound them about grades or SAT scores so they "can get into college on a full scholarship." Don't push them into athletics at the expense of music, drama, the Spanish Club, or anything else. Don't force them into Scouts or church programs or anything else, hoping it will be their ticket to college. Have them develop BALANCE - a mixture of activities. Yes, they should work at their courses, but they shouldn't obsess about grades. No one should freak out about failing a test or missing some homework assignments, especially in the early grades. Encourage play and creative activities. If you want to put them in dance or karate or town recreation basketball, fine. But not because you want them to move to the head of the pack when it comes to financial aid. Don't over schedule them - the colleges do NOT want those kids! They want kids who can make choices and who can function when not every moment of their lives is on a pre-programmed routine. Some balance of class work, test scores, a part time job, some extra curricular activities (school, private, religious, non-religious, whatever), and a social life will give your children the well-rounded life with some leadership skills and some participatory skills that they will need in life and in college.
My son was not an academic superstar. He didn't do well on the SAT but he did do much better on the ACT. Schools take whichever one the student wants to submit - and who knows if those tests will even be used much when your kids go? He was a leader, but he wasn't president of everything. He had virtually no music/art in high school but he did do community service. He had a job around the neighborhood - his own business for 7 years - mowing lawns and walking dogs and taking in neighbors' mail and generally helping out during their vacations. He was active in our synagogue, but he wasn't president of any group. He ran track and cross country for 3 years (great sports because you really run against the clock to improve yourself, not so much against the other athletes - and our school takes EVERYONE who wants to join). He was a co-captain for a couple of seasons, he mentored younger runners, he volunteered at the running "clinics" designed to encourage younger kids, he helped run some awards dinners, he learned to do public speaking as he helped host these events - so he wound up interviewing well because he knew how to speak to others. He got good references as someone who worked hard and persevered - not as someone who was always at the front of the pack. The colleges LOVED that he was well-regarded by so many. And he was far from the only one in his school who was like this.
Please forget about athletics-only scholarships. It's too much stress and it will change the way you parent your children. Please let them be who they are going to be - that doesn't mean they sit around and play video games all day, but it does mean to give them a chance to explore all the opportunities out there. You will have happier, well-adjusted children who will be in demand by any of a number of great colleges (of which there are hundreds in this country). Please be more open to the opportunities that are there if you only look!
