This task is used with third graders to develop fractional number sense along with visual and spacial awareness. Students must look at a square that is broken into different sized parts and determine if one fourth of the square is shaded. This requires students to understand what one fourth looks like. Students must understand that four fourths make a whole and be able to see this visually. The problem asks students to critique a student prediction by agreeing or disagreeing and creating an argument.
