My students have been having great math dialogue involving graphing! We just recently created a birthday graph of the birthdays in our class and we graph the weather daily. I created "Letters Around the Room" graphs, as well as "Numbers Around the Room" graphs. I have students grab a clipboard and be "Clipboard Cruisers" around the room to graph the letters that they find. Before the center is over, I have students talk about their graphs, what they notice about them, which letter/number has the most, which letter/number has the least.
