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 K-12 education (4th edition, 2004) (http://www.mcrel.org/standards-benchmarks/.) 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 K-2

Benchmark 4: Understands basic whole number relationships (for example, 4 is less than 10, 30 is 3 tens)

Grades 3-5

Benchmark 5: Understands the relative magnitude and relationships among whole numbers, fractions, decimals, and mixed numbers

Grades 6-8

Benchmark 2: Understands the characteristics and properties (for example, order relations, relative magnitude, base-ten 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 K-3

Benchmark 3: Understands basic estimation strategies (for example, using reference sets, using front-end 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 K-2

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 non-standard units

Benchmark 4: Makes quantitative estimates of familiar linear dimensions, weights, and time intervals and checks them against measurements

Grades 3-5

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 6-8

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 real-world problems

Benchmark 8: Selects and uses appropriate estimation techniques (for example, overestimate, underestimate, range of estimates) to solve real-world problems
