## Reflection: Developing a Conceptual Understanding What's Your Value? - Section 4: Group Activity/Exploration

Place value is a really important concept for the students.  Without the understanding of place value, the students will not be able to master a lot of upcoming skills.

In this lesson, by asking questions on the group activity sheet, I was able to get the students to see that each place is 10 times greater than the place to the right. Also, the students were able to write out each number in the place value chart.  This gave the students the understanding that each place can only hold a 1-digit number.  Each digit has a value.

Also, the place value chart really helped the students get a visual understanding of how to write the expanded form of a number.  The students can clearly know the value of a number from the expanded form.

By giving the students a prize at the end, it made the lesson more exciting for the students.
