Here is what I am planning for my classroom this August with Montessori materials/lessons and my other stuff I love. During work time the first few weeks, I will present a lesson to a small group while the other kids are doing something else. The something else at this time, includes DVD center, computer center, listening center, and then maybe some cut and paste things. I may introduce cutting strips to the whole class. Many of the lessons I will be doing at first are the ones for 4 year olds and I teach first grade. However, since my students have no Montessori experience prior to now and some are developmentally delayed, I think it will work well to get the foundation started.
At first I am going to hold a Language/reading work time in the morning and a Math work time in the afternoon. These may evenually mesh as the tasks get longer and students will need more time to complete activities.
I plan on doing the pink tower presentation as well as presentations on getting work, setting up work, work rules to the entire group as our first lesson and then break up into small groups. This way I can focus on student's individual needs for lessons.
