Big Ideas: There are an infinite number of different names for a given fraction. Saying two fractions are equivalent is saying that the two fractions are different names for the same quantity. This lesson builds on the third grade work with comparing simple fractions by reasoning about their size. The task uses visual models of fractions in sets to build an understanding of equivalent fractions. They will generate equivalent fractions for a visual model and develop an understanding of the patterns in the numerators and denominators of equivalent fractions. This lesson builds towards understanding addition and subtraction of fractions as joining and separating parts referring to the same whole. Vocabulary: fraction, whole, numerator, denominator, equivalent, compare
