One of my all time favorite ways to use Post It Notes is to encourage students to think about their reading. I often use blank ones to have students respond to a question or prompt that I give when I set the purpose for reading in my guided reading groups.
However, I also love to use them to help students think about their strategy use during their reading. I will give students Post It Notes that I have printed and have them jot down notes about how their strategies helped them get past tricky spots. I especially like to do this when I am working on decoding with a group. After the students read, the Post It Notes help them remember what they did and how it helped, which allows them to participate in discussions about the strategies.
I am sharing a document I made with some of the reading strategies I use. These strategies come from a book by Creative Teaching Press called Reading Strategies That Work.
