Help students understand why computational procedures with fractions make sense.

In order for students to become proficient with computational procedures when working with fractions, they need a strong understanding of why those procedures make sense. Teachers should focus on building conceptual understanding and developing procedural fluency, emphasizing that the two are connected. This teaching for understanding requires teachers to have deep knowledge of computational procedures, be fluent with a range of representations, and know common misconceptions that interfere with students' understanding operations with fractions.
