# Standards for the lesson planAlgebra: Growing Rock Candy

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

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

Standard 3: Uses basic and advanced procedures while performing the processes of computation

Benchmark 5: Performs basic mental computations (for example, addition and subtraction of whole numbers)

Standard 4: Understands and applies basic and advanced properties of the concepts of measurement

Benchmark 2: Selects and uses appropriate tools for given measurement situations (for example, rulers for length, measuring cups for capacity, protractors for angle)

Benchmark 5: Understands that measurement is not exact (i.e., measurements may give slightly different numbers when measured multiple times)

Benchmark 7: Selects and uses appropriate units of measurement, according to type and size of unit

Standard 5: Understands and applies basic and advanced properties of the concepts of geometry

Benchmark 1: Knows basic geometric language for describing and naming shapes (for example, trapezoid, parallelogram, cube, sphere)

Benchmark 2: Understands basic properties of figures (for example, two- or three-dimensionality, symmetry, number of faces, type of angle)

Benchmark 4: Understands that shapes can be congruent or similar

Benchmark 5: Uses motion geometry (for example, turns, flips, slides) to understand geometric relationships

Standard 9: Understands the general nature and uses of mathematics

Benchmark 1: Understands that numbers and the operations performed on them can be used to describe things in the real world and predict what might occur

Benchmark 2: Understands that mathematical ideas and concepts can be represented concretely, graphically, and symbolically
