Meet the women you don't know, behind the mission you do. So proclaims the poster for the hit film Hidden Figures. From tagline to title, it's clear that this story, about the black women who led NASA's team of mathematicians during the Space Race, was previously cast in the shadows of American history. Shining a light on these hidden histories, and broadening the spectrum of inquiry into the past, is not just a winning formula at the box office. It's also an endeavor that's resonating in K-12 classrooms, with teachers seeking ways to provide more accurate, complex, and engaging history education.
