Wow those do look tricky. From the photo it's difficult to see how they are assembled. Are there basically 9 smaller patches that go together, or are those longer strips continuous across the block?
I guess I would break it up into a 9 patch if it's not and then have her do the blocks assembly line style.
The 4 blocks that are in the center of the sides could be strip pieced, which would be a good place for her to start. Then do the SIS centers.
Then I think I would break up the corner blocks into mini 9 patches. squares with HST in the corners...
Same effect with a bit less fiddling maybe???
