The purpose of this task is for students to solve a mathematical problem using points in the coordinate plane. This task also helps lay the foundation for understanding operations on signed numbers without formally introducing those notions, which are not expected until 7th grade (see 7.NS.1).
Theresa Ann Lane Haggard is around 56 years old. She was 33 in 1993 when she married Merle, who was 56 then (born April 6, 1937). She was his 5th wife.
She was born in 1910, and lives in Plymouth, Michigan, twenty years before her beloved Packard. She's been driving since she was 8 years old, and officially received her license at 12, after her father died. In an appearance at the Concours d' Elegance last month, Dunning recounted her start as an automotive aficionado. I'm just a farm girl, and my dad had a lot of machinery, and I adored my dad, she said.
