Storyboard Text

  • Alright class, today we are going to be learning about Radicals. Does anyone know what a radical is?
  • Nope, not even a clue.
  • Well, a radical is an expression containing a radical symbol. It looks like this.
  • The radical symbol means 'square root'. A square root is a number that produces a specified quantity when multipled by itself. For example: 5 x 5 = 25. When asked for the square root, it would look like this: √25 = 5.
  • Write this in your notebook please.
  • Now, there is something called perfect squares. A perfect square is when you have a number that goes evenly into another number when multipled by itself. For example: 9 is a perfect number. Since 3 x 3 is 9. The 3 is multiplied 2x = a √ square.
  • Finally, you need to memorize your square roots by the end of the week. We will have a pop quiz. You must memorize 1 - 10. 1x1=1, 2x2=4, 3x3=9, 4x4=16, 5x5=25, 6x6=36, 7x7=49, 8x8=64, 9x9=81, and 10x10=100. Good luck!
  • Yep!
  • Easy.
  • Consider it done.
  • ZZZ..
  • Finally I got through to you guys!
