1 Square Roots: Math -7NOTES DATE: ______/_______/_______ 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. NAME: This square represents which perfect square #? The square root of this square is _______________ because it is a 4 x 4 square. The square root is the length of the _______________ of the square. Perfect Square #’s: Square Roots: 1² = _____ 2² = _____ 3² = _____ 4² = _____ 5² = _____ 6² = _____ 7² = _____ 8² = _____ 9² = _____ 10² = _____ 11² = _____ 12² = _____ 13² = _____ 14² = _____ 15² = _____ 16² = _____ 17² = _____ 18² = _____ 19² = _____ 20² = _____

2 Perfect square EXAMPLES: 1.√64 = 2. √225 = 3. √ 36 = 4. √ 169 = NON-PERFECT SQUARE # EXAMPLES: Between which two consecutive whole numbers do the following #’s fall between? 1. √22 lies between _____ and _____. 2. √54 lies between _____ and _____. 3. √133 lies between _____ and _____. 4. √320 lies between _____ and _____. 5. √ 400 = 6. √ 25 =
