I'm not sure what pattern you are using so I'm not sure why it's not coming out square. I understood your description but not being familiar with the pattern......makes it hard to click in my head.
If it were me working with my grands (which I DO try to get them to learn sewing, even the boys) I would leave extra fabric, then square it. The only other suggestion I have is to square it after sewing and add a border to each square to get the desired size.
I think she did an amazing job. How old is she? My 13 yo dgd is here with me and working on learning the sewing machine and how to sew. I'm so terrifically glad she wants to learn, too.
Hugs,
