"Let's talk about equivalent fractions," said JPS math coordinator Denise Pusateri to a group of third- through sixth-grade teachers. "With the new Common Core Learning Standards, we will begin talking about equivalent fractions in the third grade. They are the heart of learning about fractions. If students can understand equivalent fractions in the third grade, it will make their math education in fifth and sixth grade so much easier. A phrase I want you to take back to the classroom for equivalent fractions is, 'modified by 1.' We want students to understand that we are not changing the value of the fractions, only that it looks different but still holds the same value. This can be a difficult concept for them to understand. Let's go over some ways to help them."
