# Q1, W4: September 7-10 Pre-Algebra

Teacher Kristin Andreason Pre-Algebra 8 September 7-10 Focus One: Rational and Irrational Numbers
Standard(s) Taught

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 (e.g. π2).   For example, by truncating the decimal expansion of 2, show that 2is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.

Learning Targets and Learning Criteria
• 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.
