Writing Magic Squares
If you like to experiment with Magic Squares, or if you use them in classes, here is an accessible way to create them. This doesn't depend on a single placement strategy or a complex formula, but on patterns that are visible in any magic square.
Using a few steps and a manageable amount of trial and error, students can create 3-by-3 and 4-by-4 magic squares. This is appropriate for students in Grades 3 and up who are reasonably fluent in 2-digit addition and subtraction.
Below is a procedure outlined in an activity I have in my TPT store. You can download these steps to use yourself or give to your students. The whole activity is an introduction to solving magic squares and includes many magic squares for students to complete.
