Q1, W4: September 7-10 Pre-Algebra

TeacherKristin Andreason
Subject AreaPre-Algebra
Grade Level8
Week #September 7-10
Unit of InstructionFocus 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 LaTeX: \sqrt{2}2, show that LaTeX: \sqrt{2}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.
