Use models of rectangles with equal parts to learn to subtract fractions with unlike denominators. Multiply the denominators and then create equivalent fractions with the same denominator. Then subtract the fractions
A. Add fractions with like denominators
B. Rewrite an improper fraction as a mixed number
C. Add fractions with like denominators and rewrite the sum as a mixed number
D. Divide shapes into an equal number of parts (precursor to finding common denominators)
E. Add fractions with unlike denominators (multiply denominators to find a common denominator)
F. Rename fractions with unlike denominators (Level 1)
G. Rename fractions with unlike denominators (Level 2)
H. Add fractions with unlike denominators and rewrite the sum as a mixed number
I. Add fractions with unlike denominators and rewrite the sum in simplest form (Part 1)
J. Add fractions with unlike denominators and rewrite the sum in simplest form (Part 2)
K. Subtract fractions with like denominators
M. Subtract fractions with unlike denominators
N. Rewrite a mixed number as an improper fraction
O. Subtract a fraction from a mixed number with like denominators (rename the mixed number as a fraction)
P. Subtract a fraction from a mixed number with unlike denominators (rename the mixed number as a fraction)
Q. Subtract a fraction from a mixed number with unlike denominators and rewrite the difference in simplest form
R. Subtract a fraction from a mixed number with unlike denominators to solve a word problem
S. Subtract a fraction from 1 whole to solve a word problem
T. Subtract two fractions from 1 whole to solve a word problem
U. Add fractions to solve a word problem
