Access to Thousands of FREE Resources During Teacher Appreciation Week
We all owe much of our success in life to teachers everywhere. We at Learning A–Z want to thank educators the best way we know how—by opening up access to our websites. Last year during Teacher
Appreciation Week, we held an Open House that provided FREE access to ALL of our educational websites. Response was so overwhelming that we are going to do it again, and for even longer!
Explore Six Websites Bursting with Materials
Each day during this year’s Teacher Appreciation Week, May 5–9, plus May 12, Learning A–Z will open one of its six password-protected websites. This will allow teachers to leisurely explore all of Learning A–Z’s resources, including our newest website for differentiated instruction, Science A–Z.
We invite teachers everywhere to sample the Internet-delivered books, lessons, activities, and worksheets—for FREE.
