If you want 'easy', I'd go with the HST/square suggestion for the block with the triangles. That would essentially make it a Contrary Wife block. The major disadvantage is the added seams which could be very obvious depending on the fabric choices. Cutting and construction at:

The other block is a simple Shoofly with an altered color placement. Cutting and construction at:

Personally, I'd do the full, larger triangles for a more polished look. Nothing needs setting in, just add the small triangles to the squares, sew the vertical seams, then add the larger triangles. The smaller triangles could be added oversized and then trimmed to fit which would eliminate having to worry about the exact placement of the ears.
