Standard: 8.NS.1 Know that real numbers are either rational or irrational. Understand informally that every number has a decimal expansion which is repeating, terminating, or is non-repeating and non-terminating.

Vocabulary for this standard: rational, irrational, repeating, terminating, non-repeating, non-terminating

EngageNY module link – This unit requires familiarity with right triangles and the Pythagorean Theorem – it is in Math 8 Module 7

Quick thoughts: My strategy here is to use mini-lessons and games reinforce vocabulary upfront, do some standalone exercises so that Module 7 is more about the cognition of the Pythagorean Theorem and Right Triangles than introducing rationality concurrently.

An

**integer**is a whole number that is not a fraction.A

**rational**number is a number that can be written as a ratio where the numerator and denominator are integers.An

**irrational**number is a number that cannot be written as a ratio of two integers.A

**repeating**number is a number whose digits are repeated indefinitely.A

**nonrepeating**number is a number whose digits no not repeat. It can be terminating or non-terminating.A

**terminating**number is a number with a finite number of digits.A

**non-terminating**number is a number with an infinite number of digits, but that does not always repeat a sequence.Vocabulary practice:
