Call them by tables and ask to sit. Choosing one student from each table ask them to bring tablecloth and markers, and give worksheets to every student up their tables.

Give them instruction to mark with cross the things we don’t do in airplanes and with checking mark the things we do, than color all the pictures. 

This is not an easy task but challenges kids to find out the things we don’t do in airplanes for everybodys comfort, and things we do for our safety. Choosing the things by their own helps them memorize it better and coloring add to it a bit of creativity. It also allows them to remember such simple shapes as cross and checking mark and their common meaning.
