Clip 9/43: Standard 6: Attend to Precision Using Fractions Part 3B
Overview
Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning.
Michelle Makinson and her students work with a number line representation for a new fraction: 1 & 1/5. She identifies that a mixed-number fraction is a new concept for some students. She challenges them to create, consider, explain, and defend their number line representations to other students. With the fifth representation of a fraction, she gives students the choice of what representation makes the most sense to them. Most students select an area / set model representation.
