Using Properties of Rational and Irrational Numbers

Students explore standard HSN.RN.B.3 with this playlist. They will work to understand why the sum or product of two rational numbers is rational. Students will learn 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. Students also have the option to view instructional videos and complete practice quizzes or activities.
