[This is supposed to be a crossword puzzle.  Unfortunately blogger formatting can't handle a crossword puzzle.  So I'm just going to post the questions and answers here.  To make it into a crossword, go to a free crossword puzzle maker site, like Amored Penguin.  These questions are for young learners to teach them the difference between past simple and past continuous.  The answers are in the []brackets.]

Update:  To make this slightly more interesting, another option is to crop the worksheet on the photocopier so that students get only the grid (and not the questions) and post the questions around the room.  Questions for posting around the room are below, and on Google (drive, docs, pub).  The grid (without the questions) is also on Google (drive, docs, pub)
