I just researched common core a little and realized it only applied to my youngest and only in HS.
Aside with helping with 4th grade mission projects, I didn’t get too involved in my kids’ schoolwork, as I am unqualified to do so. I left that to the professionals … their excellent public school teachers and after-school programs they attended.
I have the utmost respect for public school teachers. They manage to get the best out of their students often with few resources. I don’t have the skills or patience for it. CVESD and SUHSD have the best teachers … just incredible. And a high percentage of them have a LOT of experience. Many of them stay on past retirement age even though they could have retired yesterday for the same monthly pay. They just love what they do.
