I'm trying to design a math block for a First Grade classroom. I've got about 60 minutes to work with. I plan on starting out with the lesson for the day using the Gradual Release of Responsibility Model: Teach, Model, Guided Practice, Independent Practice. [30 minutes] Then I'd like to have time for some workshops/centers/rotations. [30 minutes] What does your math program look like? I'd love to gather some more ideas!
