Hi, so I am about to be a student teacher this semester starting at the end of January. I have access to the online curriculum for my school but it kind of just looks like a bunch of goals and standards for each unit. I am just curious as to how teachers actually decide what to teach? The units say that they should be 20 days long. For example, theres an "informational text" unit with standards and goals for the students to meet, but how does a teacher decide what the course of action is/what to teach basically.
