If the school uses new, professionally developed programs to study subject, then the teacher shouldn't do additional work. I know that at my daughter's school, the teacher uses well-written middle school science lesson plans that fit perfectly with the state's recommended curriculum. I know that many schools have already appreciated modern educational programs. I hope that all schools in the state will switch to these programs as soon as possible, which are really interesting for children.
Yeah, I understand your point. I think that this article that I've read recently could be interesting for you too since you've been into this topic. It's a guide one Adjectives' Degrees of Comparison and the examples for each. You can read it there. Hope you would like it though.
