We do freeschooling / unschooling / selflearning.  Foundation phase I teach them the fondamental basics, reading, writing and math. Give them lots of play time and pencils and paper.  But we keep it short and fun. And have access to books all the time. If they can read, they can teach themselves. In my opinion, children learn far better in a playful environment. If you keep it short, they have time to process what they learned and not get overwhelmed.

As they get older I observe what interests them and help open the possibilities to get better at them. If they have particular interest, find an online course, YouTube videos or books about it. We don't  do grading, we don't do curriculums and we don't have set "time" for school. Life is school.

Each child is different and so is the way they learn and take information in.

I feel the traditional way of education is dead and we live in a time where education and information is free.

I am not from the US though.
