Email VS Instant Message

This week my students went to Cyber Space. In order to solve the mission they had to send an instant message. We talked all about the differences between snailmail, email, and instant messages. I just received an email from one of my 3 year old student's mom. She said when she was driving her daughter home from school her daughter said, "Mommy what's better and email or an instant message?" I love it! Her mom loved it too!
