What this is for: These cans contain mystery letters or words that make up a mystery message. The letters may spell a child's name, high frequency word or spelling word. The mystery messages may be a question about a text or subject area that students need to answer or a journal guide question.
How I made this: Pictured here are plastic juice containers (the kind that hold frozen juice mix.) I taped legal sized envelopes around the cans with packaging tape. The letter "tiles" and words are written on plastic lids that come from drink bottles. (Most of mine came from soy milk containers). I used color coding so that the words or letters matched the color of the question mark on the can.
