The free activities are immediate downloads. If you click the ‘download PDF’ button, then enter your name and email address, and click the ‘Submit and Download’ button, it automatically downloads (you don’t have to click the box to subscribe if you don’t want to, but you will need to enter your information for each free download). You can use any browser, but I find Chrome is the easiest. I also recommend using a computer and not a mobile device. Please make sure you don’t have any pop-up blockers or anything similar enabled that could block the download. Once you download it, it should open automatically or you can find it in your downloads folder. Make sure you have a PDF viewer, such as Adobe Reader installed.
