I grew up in SoCal and went to school from 65 to 78, we NEVER were taught with the “New Math”, but we were told about it and YES we learned to read and write using Phonics.
So how did this happen if these programs were replaced in 1962 and 1931 respectively??
Not All school districts complied, especially before we had Unions.
Fair question. The US has vast differences state to state, and school district to school district.
Some districts might get rid of sight-words for 10 years, then a new super is appointed and reels the locals back in.
