Everyone gets a square with a quarter circle, this is the end result- could be a good ice breaker beginning of year activity. Each student decorates the square and includes their name. Nice way to decorate the bulletin boards in the beginning of the year!
(Modify for tertiary) This is a great anchor chart for inquiry. Students write what they see, think, and wonder about the question. They can put sticky notes up so that the anchor chart can be used again.
