My daughter learned an essay format in school for writing nonfiction. This format consists of a topic sentence, followed by three fact-based sentences, followed by a conclusion. She loves this format, and has been writing little essays about various topics at home: Halloween, Christmas, friends, etc.
We were nearly late for school the other day because she had to come up with one more sentence about Halloween. What I especially enjoy about these essays is that the conclusions always start with "Clearly." As in "Clearly, I have told you all about Halloween."
I also love the phonetic spelling in the essays. She is much too impatient to get her ideas on paper to stop and ask for help with spelling. So she just writes away, as the words sound. Sometimes this makes the essays a little difficult to decipher, but she's always happy to help.
This path to literacy gets more fun every day.
