Teaching kids to think while reading is a goal I continue to reinforce all throughout the year. We talk about the text to text, text to self, and text to world connections that are explained fully by Debbie Miller in Reading With Meaning: Teaching Comprehension to the Primary Grades.
I would recommend this book to all librarians and teachers of primary children. Demonstrating how to make the connections while reading is a very valuable tool that can be shown and practiced every time books are read aloud to children.
I tell the kids that when they run and play they are exercising their bodies, but when they think and make connections while reading, they are exercising there brains.
