What children learn in Level 42

Commas have lots of jobs. Job one: after an opening phrase or a part that starts with a word like when. After school, we played tag.
Job two: around the name of someone you're talking to. Mia, please pass the salt. Come here, Leo.
Job three: after yes or no at the start of an answer. Yes, I finished my homework.
A comma can change everything! Let's eat, Grandma! means it's time to eat. Without the comma, it sounds like you want to eat Grandma!
