 Learning Goal: How to find squares and square roots of whole numbers. Learning Goal

 Square number: a number that has an odd number of factors  The number 9 is a square number because of its factors 1, 3 and 9  The number 4 is a square number because of its factors 1, 2 and 4  A number times itself always equals a square number What is a square number?

 We can get 49 by multiplying the whole number 7 by 7 (by itself)  We write 7 x 7 = 7 2  We say 7 squared  When we multiply a number by itself, we square the number. Squaring and taking the square are inverse functions, they undo each other  7 x 7 = 49  7 2 = 49  √49 = √7 2  =7 Squaring and Taking the Square Root
