Past Simple Crossword Puzzle

(TESOL Worksheets--Past Simple)
[This is a crossword puzzle made using armoredpenguin.com.  The question paper is on Google Docs here, and the answer paper is here (and embedded below.) When I use this in class, I crop the question paper so that the students only have the crossword grid, and the questions are hidden all around the room.  The questions to cut up and hide around the room are on Google (drive, docs, pub), and also pasted below.  This crossword puzzle was designed to supplement a lesson from the Lifestyle Intermediate textbook, and the choice of verbs reflects the verbs used in that lesson.]
