When I went to high school girls could only take Home Ec, they could not take Shop--only boys could--and vice versa. These days either gender can take the class they would like rather than having it limited to one gender or the other so it would now be considered gender neutral. With toys it would be that dolls would not be considered to be only for girls or trucks only for boys. The intent is to stop putting limitations on what people can do simply because of their gender.
Boys and girls had to take both in 7th & 8th grade when I was in school.
