Reflection: Developing a Conceptual Understanding Dividing a Decimal by a Whole Number - Section 2: Skill Building/Exploration

 

As I reflect over this lesson, I think about how using money helped the students understand the concept from a place value standpoint.  Because money is something that is near and dear to the hearts of students, I decided to use it to gain their attention.  By displaying each number with the appropriate money, it helped the students see what it means to divide a decimal.  When the money could not be divided into the appropriate number of groups, the students exchanged that value of money for money of another value that equalled the same amount.  I believe that this gave the students a conceptual understanding of dividing decimals.
