## ◂Math Worksheets and Study Guides Fourth Grade. Decimals/Fractions

### The resources above correspond to the standards listed below:

#### U.S. National Standards

N.1. Number and Operations (NCTM)
1.1. Understand numbers, ways of representing numbers, relationships among numbers, and number systems.
1.1.3. Develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers.
1.1.5. Recognize and generate equivalent forms of commonly used fractions, decimals, and percents.
N.2. Algebra (NCTM)
2.3. Use mathematical models to represent and understand quantitative relationships.
2.3.1. Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.
N.11. Grade 4 Curriculum Focal Points (NCTM)
11.2. Number and Operations: Developing an understanding of decimals, including the connections between fractions and decimals
11.2.1. Students understand decimal notation as an extension of the base-ten system of writing whole numbers that is useful for representing more numbers, including numbers between 0 and 1, between 1 and 2, and so on. Students relate their understanding of fractions to reading and writing decimals that are greater than or less than 1, identifying equivalent decimals, comparing and ordering decimals, and estimating decimal or fractional amounts in problem solving. They connect equivalent fractions and decimals by comparing models to symbols and locating equivalent symbols on the number line.
