Section 1
Model Subtracting a Fraction from One on a Number Line
Property
To subtract a fraction from one whole, first rename 1 as a fraction with the same denominator as the fraction being subtracted.
Then, subtract the numerators.

Section 2
Model Fraction Subtraction with Area Models
To subtract fractions with like denominators using an area model, first shade the parts for the starting fraction (the minuend).
Then, cross out the number of parts being subtracted (the subtrahend).
The number of remaining shaded parts represents the difference.
