This video addresses Indiana Academic Standard for Math 5.C.7:Use visual fraction models and numbers to divide a unit fraction by a non-zero whole number and to divide a whole number by a unit fraction. (5.C.7) Math education consultant Ryan Flessner helps educators envision the teaching and assessment of this standard in Grade 5.

When dividing fractions in fifth grade, teachers should focus students’ attention on conceptual understandings over rote memorization of procedures. Students should strive to build strong understandings of concrete, visual, and pictorial representations before they are introduced to the standard U.S. algorithm in sixth grade. Educators should take special note of this standard’s focus on division of, or by, a unit fraction.

As with the multiplication of fractions standard, visual fraction models (e.g., fraction circles, fractions bars, pattern blocks, number lines) provide students opportunities to develop strong concrete, visual, and pictorial representations when dividing fractions. Lessons should build on students’ number sense related to fractions. Teachers can use observations and one-on-one conversations to informally assess students’ knowledge as they use manipulatives and other tools to grow their understandings. Formal assessments should remain focused on visual representations of division with fractions.
