This article features the achievements of women through four picture book biographies, all of which are National Council for the Social Studies Notable Trade Books for 2011. These notable trade book selections underscore the contributions of four distinct ethnicities, symbolizing the cultural diversity of our nation and its citizens. They draw attention to women who accomplished great things, yet remain unknown and invisible in the historical record. The contributions of these women are highlighted, and developmentally appropriate extension activities are shared to help teachers encourage children to learn more about the lives of women who changed our nation not only during Women’s History Month, but throughout the year. Finally, this article discusses tips for engaging both girls and boys in the study of women’s history.
