Each lesson contains a PowerPoint presentation and a Teacher's Guide PDF file. In some cases, lessons contain other supplementary files that are referred to in the Teacher's Guide. Please note that there is a stand-alone Glossary file containing definitions of bold terms throughout the Teacher's Guides. All PDFs can be read with Adobe Acrobat or Preview (Mac OS). Some of the PowerPoint presentations have embedded video files. Your computer must have QuickTime or Windows Media Player to play these videos. If the videos do not start automatically when clicked in the slide show presentation, try opening the video files directly from the lesson folder
