This online activity offers students a chance to analyze possible patterns for the 50 stars on the US flag. Students determine the possible patterns using the clue that each row contains either one more or one less star than the row next to it. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The activity features a solution hint and a solution that suggests two ways to think about the problem and shows all possible star patterns based on the clue. The related questions challenge students to experiment with numbers to find other patterns based on numerical clues. Background information about flags and an artistic extension to the activity are included. Copyright 2005 Eisenhower National Clearinghouse
