Women and Shema in Shacharit

Women are not required to say the full shema or the blessings before it.  Even if women do not say the whole shema, it is proper for them to say the first line of the shema and baruch shem kevod malchuto l'olam va'ed.
Note If women say entire shema, even though they are not required to do so, it is a mitzva.
