# Q1, W2: August 23-27 Pre-Algebra

Teacher Kristin Andreason 8th Grade Pre-Algebra 8 August 23-27 Focus 1: Rational and Irrational Numbers
Standard(s) Taught

MAFS.8.NS.1.1:  Know that numbers that are not rational are called irrational.  Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually and convert a decimal expansion which repeats eventually into a rational number.

Learning Targets and Learning Criteria
• Students will learn the difference between rational and irrational numbers.
• convert a rational number into a decimal.
• classify a number as a rational or irrational based on whether the decimal form is repeating, terminating, or does not repeat or terminate.
• convert a repeating and terminating decimal into a rational number (fraction).
