In Computer Decoder: Dorothy Vaughan, Computer Scientist, elementary-aged children follow Dorothy's journey from math teacher to human computer and beyond, a journey made difficult because she was an African American woman working during a time of segregation. Dorothy worked incredibly hard to meet the challenges that greeted her at every turn and rose to the level of supervisor, the first black supervisor in the history of her company! But another challenge awaited when a mechanical computer threatened to replace the teams of human computers. How will Dorothy figure out this problem?  Nomad's unique approach simultaneously grounds kids in factual knowledge while allowing them the space to be curious, creative, and critical thinkers.
