This math topic focuses on identifying equivalent fractions using images of rectangles. It serves as an introductory exercise into understanding and working with equivalent fractions, where each problem requires students to view a rectangle divided into parts, some of which are shaded, and find a fraction equivalent to the displayed ratio of shaded to total parts. Each question provides two fractions as possible answers, from which the correct equivalent fraction must be chosen. This forms the basic understanding necessary for deeper explorations into fraction equivalence. It's part of the broader theme of introducing students to equivalent fractions.
