It is a simple 9 patch, made from 9 squares of the same size. Many times, but certainly not always, the corners and center are one color and the others another. This is the first block I did and presents few hazards for a newby.
Make 3 rows and press them. When you sew them together, be sure to pin and sew so that the seam allowance on top reaches the needle before the previous seam does. This way, the patches will be locked into the right position. If you do it the other way, they will tend to be pushed apart, so that your seams won't line up. If that is not clear, I can make photos for you.
