## Reflection: Developing a Conceptual Understanding Modeling Adding and Subtracting Mixed Numbers - Section 2: Skill Building/Exploration

As I reflect back on this lesson, I realize that the students had a "blast" on this lesson.  As you can hear from the video, there was a lot of chatter and discussion in the background as the students worked on the skill.  I found that the students could use something like "shapes" to do math.  This activity showed the students that fractions can be anything.  A hexagon could be your 1 whole, just as a large pie is 1 whole.  I feel that the students have a newfound appreciation and understanding of mixed numbers.  Before, as we changed mixed numbers to improper fraction, even though we drew out models, I think that the students were not connecting the two together.  This activity connected mixed numbers with something concrete.
