This is my go to, on-the-fly sub plan. This sub plan is specific to the Nutrition Action Newsletter (NAN). I have a stack of Nutrition Action Newsletter articles for students to choose from with a bunch of the student sub plans photocopied for the times that I am absent unexpectedly. I find the NAN are interesting reads for my students. However, you can adapt the information in the sub plan to any content ares or magazine, textbook or other reading material that fits your classroom.
Students are instructed to read an article and use the T-chart method to write an essay about the main article. This plan works well for 1-day with an upper level class or a couple to few days with a lower level class. Many times I have students turn in whatever work they completed on the sub plan and I grade for effort rather than completion of an essay.
