## Unit 1: Reach for the Stars

### Overview

*At the completion of the unit, students should know that numbers that are not rational are called irrational and be able to approximate the value of irrational numbers using rational numbers. Students will also utilize the properties of integer exponents and use radicals to express square roots and cube roots as well as compare the value of numbers expressed in scientific notation. Finally, students will use real-world scenarios that require the use of the proof of the Pythagorean Theorem and its converse to solve coordinate and real-world problems.*
