I love this website because it is great for both kids and teachers. Here is the blurb from the website:
"Into the Book is a reading comprehension resource for K-4 students and teachers. We focus on eight research-based strategies: Using Prior Knowledge, Making Connections, Questioning, Visualizing, Inferring, Summarizing, Evaluating and Synthesizing. Try the online interactive activities, or click below to find out how to get our engaging 15-minute video programs."
In addition to the extremely fun and engaging comprehension games on this site, you can watch real teachers teaching real lessons with real kids! Professional development on your time.
Oh . . . and I definitely think you could use it for 5th grade too! :-)
