Most of my friends have no idea what math and reading curriculum is used in their kids public schools.

It's different with friends whose kids attend private schools - most knew it was Singapore Math.

You may like it or not - but it requires parent effort to make sure your child uses their most valuable time to learn something.

My parents didn’t care about the details of my education yet I did well. I don’t think most parents ever cared so it doesn’t explain the decline. I had discipline instilled in me however, and I am guessing that’s what is lacking nowadays.
