Van Poperin- Graphing in Kindergarten

I learned a lot this week from a lesson my mentor teacher gave and the group share out my students participated in.  Meghan had the students discuss their favorite colors and group themselves accordingly and had each of them color a sticky note of their favorite color.  She then led our students to inquire about how we could display this math data, asking probing and prompting questions like "does anyone know of a way we could show this on our big piece of paper here?" We went around the rug with student volunteers sharing their ideas and a few of them made comments like "We could each put up our sticky notes with the rest of that color, like Ashley's favorite color is pink too so we would put ours together," and "we could stack them up like we did with the connecting blocks so we could count them all and then they'd all be together."  Meghan pushed their mathematical discussion even further when she asked "But is there a way we could show how many of each color without having to count each group over and over each time?"  Jamir and Calvin then volunteered their idea which was to put a number on the top of each stack of favorites.  Jade then suggested that we put numbers on the side and it would tell us how many each group had too.  I felt as though I watched my students thinking take a few turns and twists, incorporating each new person's contributions to their working theory.
