It reminds me of one practice in communist China under Mao; university students were forced to spend some time now and then working on the land, to let them feel that they were not any better than the farmers who lived there.
But actually this is even worse.
fwiw, these are guidelines, not rules, and districts can themselves choose their curricula. I'm in the bay area, and even though SFUSD has removed algebra from middle school math and tried to remove calculus from high school, my kids' district still has an advanced math track that teaches algebra in 7th or 8th grade, allowing public school kids to reach Calc BC their senior year, and/or have an elective slot for other AP math options (Stats, etc).
