Thoughts on mothers and Father's Day being celebrated in elementary classrooms?

At my kid's school, they don't limit it to mothers who can receive these gifts. On mother's day, they make it more about education of women in history, and then will print out sheets for mothers, stepmothers, grandmothers, cousins, older sisters, etc. The students can choose the ones that apply to them without feeling separated or having to ask for a separate sheet. The same is true for Father's Day - people are asked to tell stories about their fathers, uncles, grandfathers, etc, and are then allowed to make a card and crafts for them, as well, without discrimination being implemented as to who such things can be made for.
