If I were to be able to create a curriculum , I would NOT add more “home ec” skills. I knew nothing in that department, and I managed just fine. That is something a mother can easily teach her child (sewing on a button, a hem, etc. ) Many years ago, it was more common to sew your own clothes, so there was apoint in learning to sew. Today, clothing is so cheap, that those who sew their kids clothes do not do it for economic reasons, just for hobby. Cooking also is something so easily learned. When i was in school we had a “baking class” once in a while. It was basically a free period for anyone who wasnt interested in making rice krispy treats.
What I would think is important is more emphasis on human relationships and healthy communication skills. Those are the things that really matter in life. How to treat parents, friends, siblings, how to compromise, etc. Yet, we expect them to pick up on these things through osmosis, and sadly, it works all too well!
As a teacher, I try to emphasize whatever mussar I can, but it isnt always easy if you need to cover ground and follow a text. If the subject can be something like, middos, through the prism of the Torah, that would be something…
(and btw, I believe that on the side of the boys chinuch, this is greatly lacking as well)
