What Are Cookies? Cookies are tiny pieces of information that your browser adds to a special folder on your computer to let certain websites recognize you as you move from page to page within the website, most commonly used to remember login or shopping cart info. The Lesson Builder uses a session cookie to remember you as you browse the website, so that new lessons you create are added to your library and so that your searches can differentiate between your lessons and other teachers' lessons. You can still view lessons without cookies enabled. A small percent of web users choose to disable cookies since some cookies (especially third-party cookies) are used by advertisers to track browsing behavior on other websites. The Lesson Builder doesn't do that.

How Can I Enable First Party Cookies? It varies from browser to browser. Look for an 'options', 'settings', or 'tools' selection on your browser, or perform a web search for how to do it for your specific browser. You can choose to enable all cookies, enable only first party cookies, or add an exception to allow cookies from thelessonbuilder.org.

How Can I Know It's Fixed? When you think you have enabled cookies for this site, refresh the page and this message should disappear. If you still see this message after refreshing the page, cookies are still disabled for this site.
