I have created a supplemental test page for each story in Unit Five. The stories include Two Bad Ants, The Journey: Stories of Migration, The Journey of Oliver K. Woodman, Dog-of-the-Sea-Waves, Mountains: Surviving on Mt. Everest.
Each test page has a variety of questions including grammar and reading comprehension. There are some essay questions and graphic organizers also.
I simply staple these pages to each reading test. I do allow my students to use their books so that they practice the skill of locating evidence. Some questions may require my students to use their books.
