William and Grace put considerable effort into teaching their children and several children's books resulted from this. Their joint work A First Book of Geometry, which was on paper folding for children, was published in 1905. Two further children's books authored by Grace, written to introduce children to science, were Bimbo (1906), and Bimbo and the Frogs (1907). Bimbo was the nickname the Youngs gave their eldest child Frank.
