This video helps you understand that fractions are all equal-sized parts of a whole. The video illustrates this concept by comparing fair and unfair situations, a concept that is especially relevant to younger students. This video addresses CCSS 3.nf.1: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. You can learn about the CCSS here. You can find accompanying materials and more videos like this one at LearnZillion.

This video helps you recognize equivalent fractions by using area models. It addresses CCSS 4.nf.1: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. You can learn about the CCSS here. You can find accompanying materials and more videos like this one at LearnZillion.
