Standards for the lesson plan
Geometry: Finding Pentominoes

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 1: Uses a variety of strategies in the problem-solving process
Grades 3-5

Benchmark 1: Uses a variety of strategies to understand problem situations (for example, discussing with peers, stating problems in own words, modeling problem with diagrams or physical objects, identifying a pattern)

Standard 5: Understands and applies basic and advanced properties of the concepts of geometry
Grades 3-5

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
