fraction subtraction
Subtract the parts because the whole is shrinking.
Example: 7/10 - 2/10 = 5/10 or 1/2.
whole from fractions
A denominator-sized number of parts makes one whole.
Example: 4/4 = 1 whole.
visual model
Models make fraction operations easier to understand.
Example: Visual thinking supports fraction accuracy.
