Reflection: Grappling with Complexity Adding and Subtracting Fractions and Mixed Numbers - Section 2: Mini Lesson


Many of my students had difficulty with the concept of borrowing with mixed numbers.  I related the concept to money and gave the following scenario:

"I have $3.50.  I've parked my car on the street and need 6 quarters to pay the meter.  Parking meters only take quarters."

Some of my students were able to do the math mentally, but I wanted to show students exchanging a dollar for four quarters is similar to borrowing.  I provided the Help with Mixed Number Borrowing diagram and Help with Mixed Number Borrowing1 diagram for discussion.
