I am both highly organized and intentional when creating my units. I backwards plan for both content and skill sets, ensuring that all lessons provide students with an opportunity to practice their literacy skills through structured annotation and writing strategies workshops and/or group work skills like structured student talk routines to prepare for Socratic Seminars, "checks for understanding" to prepare for papers and presentations, and lots of opportunity to discuss the content with partners before sharing in front of the class.
Most of my units start with front loading vocabulary and direct instruction on content. The rest of the unit allows students to work through the content on their own, in partners, groups, and in the full class.
