The Who Am I? puzzles consist of mathematical clues to determine a mystery number. These puzzles are solved through reading a set of clues that describe the place values within the number (t = tens and u = units). For example, the puzzle to the right includes a single clue of "The sum of my digits is equal to eighteen." Therefore, we must problem solve to find two digits that add up to eighteen. In this problem, the only possibility would be 99 as the sum of both digits equals eighteen. These puzzles support the importance of building number sense and logical reasoning.
