Again, as mentioned previously...
Go to your "My Penguin Magic" section and find your teaching info there. Scroll down your purchases list and click on the green 'learn' button.
The "My Penguin Magic" access link is that big, green label at the top, middle of each page.
Look straight up...see it? Click it!
If, for some reason, it isn't there, contact PM customer service directly by email, phone, or use the Live Chat box below in the lower right corner of each page during normal West Coast (PST) business hours.
Best wishes...
