Carry On, Mr. Bowditch

Jean Lee Latham''s Carry On, Mr. Bowditch won the 1956 Newbery Medal and occupies an unusual spot in homeschool libraries: it is a history book, a math-motivation book, and a biography all at once. Nathaniel Bowditch, born in Salem, Massachusetts in 1773, was pulled out of school at ten and indentured to a ship chandler at twelve. He taught himself algebra, calculus, Latin, and French largely from borrowed books, then went to sea and transformed the practice of navigation.

The book''s real gift is what it does for students who believe they are "not math people." Bowditch works out lunar-distance calculations by hand, teaches every sailor aboard his ship to take a lunar — including men who could not read — and eventually finds thousands of errors in the standard British navigational tables everyone had been trusting with their lives. His New American Practical Navigator, first published in 1802, is still carried aboard U.S. Navy vessels.

For families, the appeal is that the mathematics is presented as a tool for solving an urgent, physical problem rather than as a worksheet. Latham writes accessibly for grades 5-8, and the seafaring plot — storms, a shipwreck, long voyages to Manila and Sumatra — carries readers who would not pick up a biography voluntarily. Loss is handled directly; Bowditch endures a great deal of grief, and the book does not soften it.

It fits naturally into an early-republic history unit, into a maritime or Age of Sail study, and into any conversation about self-education. Pairing it with a hands-on sextant or star-chart activity turns the abstract "he took a lunar" passages into something students can actually picture.
