Standards for the lesson plan Measurement: The Size Is Right
These standards and benchmarks are from McREL's online database, Content Knowledge: A Compendium of Standards and Benchmarks for K12 education (4th edition, 2004) (http://www.mcrel.org/standardsbenchmarks/.) The mathematics portion of the database was developed using National Council of Teachers of Mathematics (NCTM) standards in addition to other nationally recognized standards documents. Standard 2: Understands and applies basic and advanced properties of the concepts of numbers Grades K2 Benchmark 4: Understands basic whole number relationships (for example, 4 is less than 10, 30 is 3 tens) Grades 35 Benchmark 5: Understands the relative magnitude and relationships among whole numbers, fractions, decimals, and mixed numbers Grades 68 Benchmark 2: Understands the characteristics and properties (for example, order relations, relative magnitude, baseten place values) of the set of rational numbers and its subsets (for example, whole numbers, fractions, decimals, integers) Standard 3: Uses basic and advanced procedures while performing the processes of computation Grades K3 Benchmark 3: Understands basic estimation strategies (for example, using reference sets, using frontend digits) and terms (for example, "about," "near," "closer to," "between," "a little less than") Standard 4: Understands and applies basic and advanced properties of the concepts of measurement Grades K2 Benchmark 1: Understands the basic measures length, width, height, weight, and temperature Benchmark 3: Knows processes for telling time, counting money, and measuring length, weight, and temperature, using basic standard and nonstandard units Benchmark 4: Makes quantitative estimates of familiar linear dimensions, weights, and time intervals and checks them against measurements Grades 35 Benchmark 1: Understands the basic measures perimeter, area, volume, capacity, mass, angle, and circumference Benchmark 2: Selects and uses appropriate tools for given measurement situations (for example, rulers for length, measuring cups for capacity, protractors for angle) Benchmark 3: Knows approximate size of basic standard units (for example, centimeters, feet, grams) and relationships between them (for example, between inches and feet) Benchmark 6: Uses specific strategies to estimate quantities and measurements (for example, estimating the whole by estimating the parts) Benchmark 7: Selects and uses appropriate units of measurement, according to type and size of unit Grades 68 Benchmark 2: Solves problems involving perimeter (circumference) and area of various shapes (for example, parallelograms, triangles, circles) Benchmark 3: Understands the relationships among linear dimensions, area, and volume and the corresponding uses of units, square units, and cubic units of measure Benchmark 6: Selects and uses appropriate units and tools, depending on degree of accuracy required, to find measurements for realworld problems Benchmark 8: Selects and uses appropriate estimation techniques (for example, overestimate, underestimate, range of estimates) to solve realworld problems
