Imagine being really hungry and only getting a tiny slice of pizza. Hey, I need a bigger piece! This video shows how fractions can be different in size, and how to compare those sizes. We look at fractions with the same denominator such as 1/3 and 2/3, and fractions with the same numerator, such as 1/2 and 1/4 . Then we compare the fractions and practice using greater than/less than symbols. Comparing fractions gives us a deeper understanding of fractions and can help us with mental math and estimation.
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
