The document discusses fractions and equivalent fractions. It provides examples of fractions representing parts of wholes like balls, rectangles, and pies. It then introduces the concept of equivalent fractions as fractions that have the same value. Examples are given of splitting pizzas between people to show equivalent fractions. Models are used to demonstrate that fractions like 1/2, 2/4, 3/6 and 5/10 are equivalent. The document asks the reader to fill in missing numbers in fraction equivalences.
