Reading
Martha Washington was the wife of George
Washington, the first president of the United
States. As a child, Martha probably had no idea that
her life would become so exciting.
Growing up, Martha lived on a large farm in

the South. She and her sisters and brothers liked to
go fishing or to run races with each other.
There were not many schools then, so Martha
learned at home how to read, write, spell, sew and
cook. She often shared her favorite “dishes” with
her pet squirrel, Maybelle.
All that she learned as a child helped Martha
later when she became First Lady of the United
States.
