Number And Operations-Fractions3
Outcomes
-
Extend Understanding Of Fraction Equivalence And Ordering.
-
4.NF.1
Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x 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.Examples
-
4.NF.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.Examples

4.NF.1
-
Build Fractions From Unit Fractions By Applying And Extending Previous Understandings Of Operations On Whole Numbers.
-
4.NF.4
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.Examples
-
4.NF.4
-
Understand Decimal Notation For Fractions, And Compare Decimal Fractions.
-
4.NF.6
Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.Examples
