This math topic focuses on comparing fractions that have the same denominator and determining which fraction is larger. It includes practice on identifying if a fraction is above or below 1. Several problems are presented where students need to choose between two fractions (with codenamed answers such as 'a' or 'b') and decide which one is greater. This is a part of a broader unit on mixed fractions. Each problem uses a "domino" metaphor, likely visualizing fractions using images to resemble domino tiles.
