These were some of my issues too in Yukon. Pretty much all teachers accepted work late with little to no penalty. Not a good lesson.My only real complaint with what I have seen so far at Piedmont Schools is their willingness to accept late work is FAR too lenient and not having actual text books to send home so I can see how they are teaching the kids so I can reinforce it at home. The second part is especially difficult for math homework and how different the methods are now versus what I learned.
And even if the textbooks were only a pdf version, at least there would be a 'source' to reference. As opposed to googling or learning the method on khan academy.
