# Q1 W2 Sept 7-Sept 11 Pre-Algebra

Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 2 Focus 1 – Rational and Irrational Numbers
Standard(s) Taught

MAFS.8.NS.1.1: Know that numbers that are not rational are call 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.

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

Learning Targets and Learning Criteria

• activate prior knowledge
• understand classroom procedures and expectations
• 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).
• estimate the value of an irrational number by rounding to a specific place value.
• locate irrational numbers approximately on a number line
• compare the size of two irrational numbers by using a number line.
• use reasoning to determine between which two consecutive whole numbers a square root will fall on a number line.
