# Q1, W2: September 8-11 Pre-Algebra

Teacher Kristin Andreason Pre-Algebra 8 September 8-11 Unit One: 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 expression which repeats eventually into a rational number.

MAFS.8.NS.1.2:  Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximate on a number line diagram, and estimate the value of expressions.

Learning Targets and Learning Criteria
• Students will be able to decide if a number is rational or irrational
• Students will learn how to convert decimals to fractions and fractions to decimals.
• Students will learn how to compare and order rational numbers.
