It actually started getting worse while I was in school. Around 4th grade, they swapped out the curriculum. I was lucky to have teachers that refused to use it. When I looked at my sister’s 5th grade math book, it was stuff I learned in 1st to 3rd grade. She’s now in high school and struggling with Algebra, and I’m not surprised.
I’ve hosted the webm and a transcoded mp4 on my servers as well.
