The Objective The student, given a whole number from 0 to 100, will identify it as a perfect square or find the two consecutive whole numbers between which the square root lies.
14
8.5 GOALS…. Identify the perfect squares from 0 to 100. Identify the two consecutive whole numbers between which the square root of a given whole number from 0 to 100 lies
15
Words to KNOW! Perfect square: a whole number whose square root is a whole Number √25 = 5 makes 25 a perfect square √16 = _____ makes 4 a perfect square Square root: when you multiply a number by itself, such as 2 x 2, you get 4, a perfect square. √ 4 = 2. 3x3 = 9 9 is a perfect square. √ 9 = 3
16
The First 10……Perfect Squares 1 4 9 16 25 36 49 64 81 100 If you square these numbers, you will find the first 10 Perfect Squares
17
The First 10……Perfect Squares √1 = 1 √4 = 2 √9 = 3 √16 = 4 √25 = 5 √36 = 6 √49 = 7 √64 = 8 √81 = 9 √100 = 10 If you square these numbers, you will find the first 10 Perfect Squares
18
More Perfect Squares….. √144 = 12 √ 169 = 13 √225 = 15 √400 = 20
19
Whole numbers? What WHOLE numbers? You will be asked to determine between which to 2 whole numbers does a number fall when you find the square root. To do so, simply enter that number in your calculator and press: √ button.
20
Finding the whole numbers…. √5 = 2.236067… This number falls between which 2 whole numbers? 2 and 3
21
Finding the WHOLE numbers… Determine which 2 whole numbers does this square root fall? √ 132and3 √ 275and6 √ 637and8 √ 113and3
