This video shows two different student-generated strategies for solving fair share problems leading to a fraction less than 1. This standard relates to Common Core standard 5.NF.3, and North Carolina standard NC.5.NF.3.

The end of this video helps teachers see how standard NF.3 can be introduced prior to NF.1 (addition/subraction of fractions with unlike denominators).
