This playlist consists of 9 videos all about Rational and Irrational Numbers.  Teachers can use these videos to support their lesson plans and engage students.  These videos each cover specific topics and concepts learned in Algebra I classes.  The playlist is an excellent resource for students to review or study for a test or final.  For Common Core alignment, see below. By the end of this playlist, students will be able to 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.
