Identify a common factor of a pair of numbers. Divide both numbers by that factor and analyze whether those quotients still have a common factor. This skill can help you find the greatest common factor and reduce fractions completely
A. Determine fractions of a whole number based on a model (Level 1)
B. Determine fractions of a whole number based on a model to solve a word problem
C. Determine fractions of a whole number based on a model (Level 2)
D. Determine fractions of a whole number based on a model (Level 3)
E. Determine a whole number given a fraction of that number based on a model
F. Multiply a whole number by a fraction
G. Relate a fraction of a whole number to multiplication and solve
H. Determine a fraction of a measurement by converting units and multiplying
I. Determine common factors of two whole numbers
K. Reduce a fraction by dividing by a common factor
L. Reduce factors before multiplying a whole number by a fraction (Level 1)
M. Reduce factors before multiplying a whole number by a fraction (Level 2)
N. Multiply a whole number by a fraction by reducing before or after multiplying
