This item primarily focuses on common core standard L 2.2 b - using commas in greetings and closing of letters. My students had a blast with the learning center this year! They even asked for another one! For this standard I have included a worksheet, learning center activity, and assessment. If you enjoy this item please check out my other TpT items. I also have the entire standard L 2.2 a-e available as a mega packet in my TpT store.
