Task# Writing a Mixed Number as an Equivalent Fraction

Illustrative MathematicsVaries

This task relates to one aspect of 4.NF3.c, namely writing a mixed number as an equivalent fraction; other tasks illustrate other aspects of this standard. The purpose of this task is to help students understand and articulate the reasons for the steps in the usual algorithm for converting a mixed number into an equivalent fraction. This concept is an important precursor to adding mixed numbers and fractions with like denominators and as such, step two should be a point of emphasis. This task is appropriate for either instruction or formative assessment.
