Here is how close reading looks in my classroom.
Notice that I'm not spending hours on this every day. This is why my students don't mind coming back to it day after day. This is also why it's so important to have an interesting selection (which is why I don't do it with every chapter in the textbook). In my opinion, it's also why close reading is so flexible in that you can do it whole class, in small groups, or even as homework.
Here are some free close reading topics that you can do with your students if you want to try close reading without having to come up with your own text selections and questions.
Here are my paid close reading products if you want to try it for a month or longer.
