Topic 6Equivalent Fractions and OrderingMAFS.4.NF.1.1 (DOK 3) Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. MAFS.4.NF.1.2 (DOK 2) Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

Vocabulary1. Fraction: A symbol used to name part of a whole, part of a set, or a location on a number line.2. Equivalent fractions: Fractions that name the same region, part of a set, or part of a segment(Example: 2/4 is equivalent to 4/8)3. Denominator: the number below the fraction bar that represent the total number of equal parts in the whole.(Example: 2/4. A pizza is cut into 4 pieces.)4. Numerator: the number above the fraction bar that represents the parts, or pieces, of the whole.5. Benchmark fraction: a fraction that is commonly used for estimating.(Example: ¼, ½, ¾)6. Common factor: a number that is a factor of two or more given numbers.(Example: Common factors of 12 and 6 are 1, 2, 3, and 6.)
