The student completes part of the problem correctly, but may fail to draw accurate models or explain reasoning. The student completes Parts (a), (b), and (c) correctly; the explanation includes some reasoning. The student correctly: Shows all of the fractions from up to numerically, including renaming the wholes. Explains or of the whole roll was eaten with an accurate model in Part (b).
