DescriptionAmy Martino introduced division of fractions by asking students to describe how many white rods equal an orange and red train. She then asked the students to name the white rod if the orange and red train (i.e., a composite rod made by laying the rods end-to-end) was called one. When the number name for the white rod was established as one twelfth, she asked the students how many one twelfths are in one. The students explained that there are twelve twelfths, or twelve one twelfths, in one.
