Dividing Fractions by Whole Numbers with Keep Change Flip

The Organic Chemistry Tutor

This concise math tutorial demonstrates the step-by-step process for dividing fractions by whole numbers. The video breaks down the procedure into three clear steps: converting the whole number into a fraction, applying the "Keep, Change, Flip" method to convert division into multiplication, and then multiplying across to find the solution. It uses four specific examples to illustrate the concept, gradually increasing in complexity. The content specifically highlights two different strategies for handling the final calculation: multiplying straight across and then simplifying the result, versus "cross-canceling" or simplifying factors before multiplying. This dual approach helps students understand efficiency in arithmetic. The video provides a clear visual demonstration of how to reduce fractions both within the equation and at the end of the problem. For educators, this video serves as an excellent direct instruction tool or review resource for 5th and 6th-grade math units on fraction operations. It effectively scaffolds learning by starting with basic procedural fluency and moving toward more efficient computation strategies. The inclusion of a "pause and try" section allows for active student participation and immediate self-assessment during class.
