Making (odd) MAGIC SQUARES (Best in Full Screen) After Clicking the Green Flag ... Use the Sliders to set the values for this Magic Square Then Click whatever's in the Top-Left corner (until the Magic Square is complete). Note: Even choices for the Size Slider are rounded up. Shows a very simple paper & pencil method to turn any n x n (n odd) arithmetic sequence of numbers into a Magic Square (where the numbers in each row, column & diagonal sum to the same value = n x middle-no) An arithmetic sequence is any sequence of values that starts starts with a specific value (S), and where each subsequent value is changed by a constant value (d). So the i-th term in an arithmetic sequence = S + (i - 1)d
Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. This project was created purely & simply for an Online Mathematics class, where I want to show students, a nice simple step-by-step process for creating an odd-sized Magic square. I used to show them on a gridded portable whiteboard in the days of face-to-face classes. It's Touch Screen friendly. Special thanks to whichever mathematics teacher it was who showed this technique to me, way back in either my latter years of Primary School (late 60s) or early years of High School (late 70s). It has stuck with me ever since, and I don't think anyone I have shown it to since, has ever seen it before.
