I’ve ranked the great website Into the Book as the number one site for Intermediate readers.
Here is how I describe it at The Best Websites For Intermediate Readers:
This is an absolutely incredible resource designed to help students learn reading strategies — visualize, predict, summarize, etc. For the past couple of years it had only been partially completed. In the course of examining sites for inclusion in this list, though, I found that all its exercises were finished. Users are led through the process of learning each reading strategy with interactive exercises.
It was a great site, and now it’s even better! They just announced a big update:
we’ve rebuilt all the Flash interactives in HTML, losing scarcely any interactivity in the process. Now students can use the website on iPads and other tablets as well as on traditional computers. We also developed new games and interactives to give students even more ways to explore and practice these strategies
