I am looking for a symbol other than a crystal ball to associate with "predicting" this is for 5th graders
as the crystal ball is commonly associated with magic I am looking for a neutral symbol to represent the exercise of "predicting" to use as a reading strategy for improving comprehension
Maybe a picture of a gypsy or a "Great Carnack" type of person.
Good Question I know this is not news to you, to grasp logical avenues.

How about a box with a question mark inside? As with all symbols, a simple explanation of this icon would be needed. Think about presents. Ask students how many have guessed a present's contents by using available clues (such as size, weight, etc.)
