Standard 2.5.5.B: Use appropriate mathematical terms, vocabulary, language, symbols, and graphs to explain clearly and logically solutions to problems

Standard 2.8.5.B: Select and use strategies, including concrete objects, to solve number sentences (equations and inequalities) and explain the method of solution.

Standard 2.8.5.C: Recognize, describe, extend, create, replicate, and form a rule for a variety of patterns, sequences, and relationships verbally, numerically, symbolically, and graphically.

Standard 2.8.5.D: Determine a functional rule from a table or graph.

Standard 2.8.5.E: Use concrete objects and combinations of symbols and numbers to create expressions, equations, and inequalities that model mathematical situations.
