Algebraic Reasoning: Prime/Composite [TEKS Tools Grade 5]

This post specifically looks at how algebraic reasoning can be used to identify prime and composite numbers. Read more about TEKS Tools and their rationale here.

Algebraic Reasoning

Algebraic reasoning, the fifth TEKS Tool, accounts for around 9% of each 5th grade STAAR test. This thinking does not use a visible tool but instead relies on applying algebraic concepts to expressions, equations, and inequalities.

The main function of algebraic reasoning is to identify patterns, use the order of operations, and understand the functioning of equations and expressions.
