Use the most frequently occurring prepositions (e.g., to, from, in, out, on, off, for, of, by, with).

Okay, so the everything-you-can-do-with-a-box trick may not work for every single common preposition, but it's a start. This substandard asks students to know the difference between in the box, on the box, coming from the box, going to the box, thinking outside of the box, and hopefully not living in the box.
