This is a variation of log cabin (called Greek Key) that is very easy to do. Hope I can explain it so you understand.
You start with 2 squares -- dark and light -- and sew them together. Next, you sew a dark strip to one side and a light strip to the opposite side. Next, you sew a dark strip to the top/bottom and a light strip to the opposite top/bottom. Keep doing this until you have a block the size you want. On the block you show, there is one extra white strip at the end.
I found a Greek Key log cabin pattern online, but it is unnecessarily complicated. If you Google "log cabin greek key pattern" you will probably find it.
This would probably work well with strips cut 2-1/2" wide, although you could go smaller.
You can pre-cut all of the strips to their correct lengths before you start sewing. If you decide on this, it's a good idea to work everything out on graph paper first.
An alternative is to start with the 2 squares sewn together, press the seam to the dark side, then sew this piece to a strip. Trim the strip to the correct size after you sew. If you Google how to strip-piece a log cabin quilt, you will see that you can stitch an entire series of squares to the strip before taking it to the cutting table.
