The big problem, however, is that most of the time their website doesn’t appear to be working. That’s the primary reason I haven’t put links to their activities on my main webpages.
They do appear to be functioning for now. Go to their main textbook site for Geography, click on one of the books, then click on any of the chapters, and then go to Interactive Features to see the best online exercises.
You can also use the main menu to go to any of their other textbook support sites.
Check them out now before it stops working again.
