I wanted to restate what Chris said~ we want to
expose them to all the sentence types. Since the beginning stages of the sentence ladder are where the teacher is doing all the writing~ and modeling
how the sentences become more complex, this is easy to do. Later they will "help me (the teacher)" and share their ideas to help construct the sentences. They will not be creating their own until much later. At that point you can differentiate the sentences that are created based on skill level. At first, you could create the first sentence and have your lower students come up with the next level (or two); then your on level to do the next (or two) and then your high students to try the highest levels. There is no telling where this will take our students for sentence writing. This year I am moving to first grade and I can't wait to see how far they go!!!!
I also wanted to add that Biff told us at the conference that we could have the students do a student ladder for step 5 of our 5~step lesson format. I tried this out with a lesson on a circle in my break~out session. It was awesome! I'm thinking that when I teach it this coming year, one of the variations I can use at the beginning is to do a sentence ladder on a concept I taught them the day before. I can't wait to see how it works!!!!
