Section 1
Model Division of a Unit Fraction with a Tape Diagram
Property
To divide a unit fraction by a whole number using a tape diagram, you partition the piece into equal parts. Each new, smaller part represents the fraction of the whole.
In this Grade 5 lesson from enVision Mathematics Chapter 9, students learn to divide whole numbers by unit fractions and unit fractions by whole numbers using area models and number lines. The lesson covers expressions such as 4 ÷ 1/6 and 1/4 ÷ 6, helping students understand why dividing a whole number by a fraction less than 1 produces a quotient greater than the original number. Students also use multiplication to check division results and apply these skills to real-world problems involving equal sharing and measurement.
