Definition:To square a number means to multiply it by itself. Considering Square A:Remember the method we followed to multiply Square A by Square B? (To review, return to Classroom Activities.) If this method can be used to 'multiply' two magic squares, let's use it to square a magic square.To square Square A, we'll follow the same steps, but instead of using Squares A and B, we'll use Square A twice. Square A Square A
Check for Understanding:Generating the second square:Following the multiplication method, we will fill the nine cells in the empty 3x3 grid. We will begin by adding the same number to each entry in Square A to make a new magic square.Square A is made up of nine entries. When we add 9 to each of them, we get We will continue this process by adding 9 to each entry to make each successive cell. |
