Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram.
3.NF.2: Understand a fraction as a number on the number line; represent fractions on a number line diagram. 3.NF.2a: Represent a fraction on a number line diagram by defining the interval from 0 to 1 as the and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line. 3.NF.2b: Represent a fraction a/b on a number line diagram by marking off a lengths of 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. 3.MD.4: Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot where the horizontal scale is marked off in appropriate units – whole numbers, halves, or quarters. 3.NF.3: Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. 3.NF.3a: Represent two fractions as equivalent (equal) if they are the same size, or the same point on the number line. 3.NF.3b: Recognize and generate simple equivalent fractions, e.g., ½ = 2/4, 4/6 = 2/3).
