Standards for the lesson plan
Number and Operations: Raul's Apples: Word Problem

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 6-8

Benchmark 3: Understands that there is no one right way to solve mathematical problems but that different methods (for example, working backward from a solution, using a similar problem type, identifying a pattern) have different advantages and disadvantages

Benchmark 5: Represents problem situations in and translates among oral, written, concrete, pictorial, and graphical forms

Benchmark 6: Generalizes from a pattern of observations made in particular cases, makes conjectures, and provides supporting arguments for these conjectures (i.e., uses inductive reasoning)

Standard 8: Understands and applies basic and advanced properties of functions and algebra

Benchmark 1: Knows that an expression is a mathematical statement using numbers and symbols to represent relationships and real-world situations (for example, equations and inequalities with or without variables)

Benchmark 5: Solves linear equations using concrete, informal, and formal methods (for example, using properties, graphing ordered pairs, using slope-intercept form)
