8.NS.1 Understand and apply the definition of rational and irrational numbers.

This is the beginning of the math portion of an interdisciplinary unit on Identity. The math content focuses on characteristics of numbers that place them in specific algebra number sets and on a unique place on the number line. After this tutorial, students will estimate square roots and investigate applications of rational and irrational numbers - specifically the Pythagorean Theorem.

Students will write a paragraph in response to a journal prompt to reflect their understanding of irrational and rational numbers. The teacher will informally review the journals to determine if students have an understanding of irrational numbers that is sufficient for application with real numbers (such as the Pythagorean Theorem.)
