I have 20 new friends. 7 friends are new to me. 13 friends and I spent kindergarten together and seeing them now two years later is really fun. Second graders are independent. Second graders know how to "do" school. Second graders can work quietly. Second graders can verbalize higher level thinking. Second graders can read independently and write lots of sentences. Second graders are eager to learn multiplication and read books. I'm eager to spend the year with them.
On a side note, I am less tired mentally and physically with just one class of students who come every day all day long. Every day is new and different and continues from the day before. Life is good, after just one week. I might just keep singing, "celebrate good times, come on!"
