129 questions5 skills
Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
106 questions6 skills
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
75 questions4 skills
Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole 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.
79 questions5 skills
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.
205 questions11 skills
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
Compare fractions with the same numerator or denominator
Relate fractions to 1
Compare fractions with fraction models
Compare fractions with the same numerator
Equivalent fractions on the number line
Equivalent fraction models
Compare fractions with the same denominator
Fractions of different wholes
Compare fractions on the number line
Write whole numbers as fractions
41 questions2 skills
Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
53 questions3 skills
Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model.
74 questions3 skills
Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
100 questions6 skills
Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
