A print with a cool classroom appropriate quote, $20
Some personalized pencils so students that borrow them don't walk away with them, $7
A plant to make their classroom a bit more cozy (just make sure it does well with artificial lighting like this fern), $31
A cute tote to carry all their graded papers to and from school, $20
Some cool tape to use for decorating their rooms or bulletin boards, $12
And if you are a parent trying to decide on a present for your child's teacher: hold off on the mugs however tempting it may be. My mom used to come home with a ridiculous amount of those during Christmas and the end of the school year. We didn't have room for all of them year after year. A heart felt note from the student is probably better. (Or a gift card to a teacher supply store, especially for new teachers. Teachers spend a lot of their own money on supplies for their classrooms on an already low salary.)
Any teachers out there with more ideas?
