Once you've decided on the lesson and the integration of tech into that lesson, let everyone know that the lesson is ready. "Publishing" can be as simple as having a Google Slides open to the public. Slide one can be your introductory slide with a video of you greeting your students. Slide two can be your first lesson with instructions, links to resources, and another video where you explain the lesson and objectives. Communicate with parents, teachers, and students where to find the link, or send the link to them.
