Arkansas Curriculum Frameworks
AR.Math.Content.4.NF. Number and Operations- Fractions
AR.Math.Content.4.NF.A. Generalize place value understanding for multi-digit whole numbers
AR.Math.Content.4.NF.A.1. By using visual fraction models, explain why a fraction a/b is equivalent to a fraction (n a)/(n ח b) 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. For example: 1/5 is equivalent to (2x1)/(2x5).
AR.Math.Content.4.NF.A.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 ). Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols (>, =, <), and justify the conclusions (e.g., by using a visual fraction.
AR.Math.Content.4.NF.B. Build fractions from unit fractions by applying and extending previous understanding of operations of whole numbers.
AR.Math.Content.4.NF.B.4. Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
AR.Math.Content.4.NF.B.4.A. Understand a fraction a/b as a multiple of 1/b. (e.g., Use a visual fraction model to represent 5/4 as the product 5 (1/4), recording the conclusion by the equation 5/4 = 5 ח (1/4)).
