Early in the semester, during a seemingly benign math lesson over money, one of the students in my second and third grade blended classroom halted the instruction to ask "Wait! Why are there no women on money? Is there any money with women on it?" Never one to miss an opportunity to get my students thinking critically, we took some time to discuss why that might be. In considering how to approach this topic in the classroom, I drew on several areas of research: the marginalization of women in history, the use of inquiry in the elementary classroom, and incorporating discussion in lessons.
