    • Review:
      What does it mean to Square a number?
      What does it mean to take the Square Root?
    • What do we do if asked to find the square root of a number and the answer is not a whole number?
      1) Use the CALCULATOR
      Round to the nearest thousandth the following numbers
      √8
      √50
      Round to the nearest tenth the following numbers
      √80 √45
    • 2) Put the number in between 2 integers
    • Putting numbers on a number line

    • Where do square roots fit in our number map?
    • ·If the square root of a number is a whole number or a terminating decimal, it's rational
      Ex :
      ·If the square root of a number is a non terminating decimal, you can be sure it's irrational
      Ex:
    • Rational or irrational ?
