This is pattern FKOQR 1-1-1-2M. It is a 4-shape tessellation, though I have combined three of the shapes into one. I shaded the design in three colors.
Color and arrange four patches to make two 4-patch blocks as shown below. The lower right patch in each block is a mirror-image of the other three patches.
Alternate rows of block A with rows of block B.
