Dylan's Multidigit Subtraction Strategy
Without having been taught a method for solving subtraction problems that require regrouping, a first-grader applies his natural knowledge of numbers and operations to solve problems containing two- and three-digit numbers. This conversation features his reasoning as he formulates an explanation of...
