M.3.R.NF.2
PriorityUnderstand a fraction as a number; and represent fractions on a number line diagram.
- a.Represent one part of a whole divided into equal pieces on a number line by using the segment from zero to one as the whole and dividing it into equal parts based on how many pieces the whole is split into. Understand that each part has the size of one divided by the total number of parts, and that the endpoint of the first part starting at zero marks the location of this fraction on the number line.
- b.Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
