The Expeditionary Learning modules have repeat skills used throughout the year and build off of each other from one year to the next. As part of the Common Core curriculum students are expected to make inferences. This is the "I Notice/I Wonder" part of the curriculum used with the 3rd grade visuals and leads into the 4th grade visuals.
I found this to be a useful reminder for students that "I Notice" refers to what we already see in the picture and that "I Wonder" refers to questions we may ask about the picture (staying focused on the w's...who, what, where, when and how).
When I taught Dual Language, the visual really helped the students to make the connection between the words "Notice and Wonder."
