  1. Today’s lesson . . . What: Square numbers and Square roots Why: To examine the perfect square numbers up to 400 and to find the square root of both perfect and non-perfect square numbers.

  2. This square represents which perfect square #?_______ This is also the __________ of the square. The square root of this square is _________ because it is a 4 x 4 square. The square root is the ____________ length of the square. 16 area 4 side

  3. = 1 = 2 = 3 = 4 = 5 = 6 = 7 = 8 = 9 = 10 = 11 = 12 = 13 = 14 = 15 = 16 = 17 = 18 = 19 = 20

  4. The PERFECT SQUARE # is the __________ of the square!!! AREA The SQUARE ROOT # represents the __________ length of the square!!! SIDE

  5. Perfect square EXAMPLES: √64 = 2. √225 = 3. √ 36 = 4. √ 169 = 8 15 6 13 5. √ 400 = 6. √ 25 = 20 5

  6. NON-PERFECT SQUARE # EXAMPLES: Between which two consecutive whole numbers do the following #’s fall between? √22 lies between _____ and _____. √54 lies between _____ and _____. 4 5 8 7 3. √133 lies between _____ and _____. 4. √320 lies between _____ and _____. 12 11 17 18
