I have created a supplemental test page for each story in Unit Four. The stories include A Mr. Rubbish Mood, The Albertosaurus Mystery, A Tree Is Growing, Dogzilla, and Life on the Ice. There is also an answer key with each test page.
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.
