## Reflection: Joy Adding Repetitive Sets of Numbers - Section 2: Teaching the lesson

The students were so excited as they began to graph the data. The graph began to emerge to look like a mountain or a skyscraper. As the middle of the graph grew higher and higher, the students couldn't wait to do the next day.

I wondered if the amount of graphing would be too much, or too confusing for students, but they became excited about the project. They worked hard and were insistent that they wanted to keep going, even when I suggested that we take a break.

They were amazed at how high days 6 and 7 were. They figured out there were 42 of each object from the 2 days.

If students can take ownership of a math project, they will see math as something fun, and something they are good at. What better foundation to set, than one that says, "I like math, I can do math, Math is fun!"
