Mystery Puzzles From Ruth Munoz, a third grade teacher at Valley View School in Duarte, California: "Do you have puzzles that are in good condition but the boxes are worn out? Throw out those boxes and create mystery puzzles! Put the puzzle pieces in a gallon size Ziploc bag. Tape an index card on the front that says the name of the puzzle and gives clues about what the picture contains. (For example, Bugs Bunny has a red shirt and blue pants on. He is working in his garden and is growing corn. A black scarecrow is next to a red barn.) These mystery puzzles will be one of your students' favorite free time activities!"
