Commast can be a tricky concept for students. Use this color anchor chart to help illustratte this concept. I use the color copy on my white board. The students have black and white copies for their interactive notebooks. We discuss them in together as a class while we discuss. There are two different size black and white copies. The files are pdf and jpeg format. There is also a manipulative that students can glue into interactive notebooks to write their own examples under each o the laps.
