Use Real Number Properties to Perform Computational Procedures

CCSS Math: HSN.RN.3

HSN.RN.3 Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.

This Algebra 1 lesson teaches students how to use the properties of real numbers to perform computational procedures. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Students will read partial equations and complete them by determining, writing, and justifying the real number property that applies (Commutative, Associative, or Distributive). Then, they will perform the operations to prove the results do not change. In addition to the lesson, there is one page of Independent Practice and three pages of periodic review.
