Mathematics, Grade 7 Fluency Statement What are the Main Messages of NCTM's Principles and Standards (2000) Regarding Computation? Computational fluency is an essential goal for school mathematics (p. 152): Embedding Fluency in Conceptual Understanding The methods that a student uses to compute should be grounded in understanding (pp. 152-55). Students can achieve computational fluency using a variety of methods and should, in fact, be comfortable with more than one approach (p. 155). Students should have opportunities to invent strategies for computing using their knowledge of place value, properties of numbers, and the operations (pp. 35 and 220). Students should investigate conventional algorithms for computing with whole numbers (pp. 35 and 155). Goals of Fluency Students should know the basic number combinations for addition and subtraction by the end of grade 2 and those for multiplication and division by the end of grade 4 (pp. 32, 84, and 153). Students should be able to compute fluently with whole numbers by end of grade 5 (pp. 35, 152, and 155). Students should be encouraged to use computational methods and tools that are appropriate for the context and purpose, including mental computation, estimations, calculators, and paper and pencil (pp. 36, 145, and 154). What is Computational Fluency? NCTM Principles and Standards of School Mathematics (2000) defines computational fluency as having efficient and accurate methods for computing that are based on well understood properties and number relationships. The National Math Panel Report cites the NCTM definition of computational fluency in its report when it uses this phrase. For further clarity, on page 3-41 of the Task Group Reports of the National Mathematics Advisory Panel, there is a discussion of the critical foundations for the study of algebra: (1) fluency with whole numbers, (2) fluency with fractions, and (3) particular aspects of geometry and measurement. Mathematics Test Specifications and Test Blueprints Page number Oregon Department of Education Office of Assessment and Information Services Mathematics, Grade 7 The excerpt from page 3-41 is below: 1. Fluency with whole numbers By the end of the elementary grades, children should have a robust sense of number. This sense of number must include understanding place value, and the ability to compose and decompose whole numbers. It must clearly include a grasp of the meaning of the basic operations of addition, subtraction, multiplication, and division, including use of the commutative, associative, and distributive properties; the ability to perform these operations efficiently; and the knowledge of how to apply the operations to problem solving. Computational facility rests on the automatic recall of addition and related subtraction facts, and of multiplication and related division facts. It requires fluency with the standard algorithms for addition, subtraction, multiplication, and division. Fluent use of the algorithms not only depends on the automatic recall of number facts but also reinforces it. A strong sense of number also includes the ability to estimate the results of computations and thereby to estimate orders of magnitude, e.g., how many people fit into a stadium, or how many gallons of water are needed to fill a pool. 2. Fluency with Fractions Before they begin algebra course work, middle school students should have a thorough understanding of positive as well as negative fractions. They should be able to locate both positive and negative fractions on the number line; represent and compare fractions, decimals, and related percents; and estimate their size. They need to know that sums, differences, products, and quotients (with nonzero denominators) of fractions are fractions, and they need to be able to carry out these operations confidently and efficiently. They should understand why and how (finite) decimal numbers are fractions and know the meaning of percentages. They should encounter fractions in problems in the many contexts in which they arise naturally, for example, to describe rates, proportionality, and probability. Beyond computational facility with specific numbers, the subject of fractions, when properly taught, introduces students to the use of symbolic notation and the concept of generality, both being an integral part of Algebra (Wu, 2001). 3. Particular Aspects of Geometry and Measurement Middle-grade experience with similar triangles is most directly relevant for the study of algebra: Sound treatments of the slope of a straight line and of linear functions depend logically on the properties of similar triangles. Furthermore, students should be able to analyze the properties of two- and three-dimensional shapes using formulas to determine perimeter, area, volume, and surface area. They should also be able to find unknown lengths, angles, and areas Mathematics Test Specifications and Test Blueprints Page number Oregon Department of Education Office of Assessment and Information Services Mathematics, Grade 7 Core Standard: 7.1 Number and Operations and Algebra Develop an understanding of operations on all rational numbers and solving linear equations.
