## Reflection: Developing a Conceptual Understanding Using Money to Understand Decimal Place Value - Section 3: Group Activity/Exploration

This activity allows a lot of movement and interaction within the classroom.  This is a perfect activity to use for MP3.  The students get a chance to challenge each others answers.  This allows for critiquing the reasong of others.

I find that students enjoy activities that allow them to move around and talk.  With this activity, the students justify their reasoning with their classmates.  It is very important for the students to hear the thought process of each other.  Also, with the lesson, by using money to help understand decimals, the students get a conceptual understanding of what each place value means.  The students learned that the tenths place is represented by a dime because it takes 10 dimes to make a dollar.  Also, the students learned that a penny represents that hundredths place because it takes 100 pennies to make a dollar.
