The online Classroom Presentation Tool (CPT) is part of the National Geographic Learning Platform, where Spark is located.
Teachers can get access to Spark by signing in to learn.eltngl.com. Credentials will be provided by your National Geographic Learning representative, or your institution's administrator.
Once signed in, click on the arrow icon 
that appears when you hover over the course you are
looking for.
Within the course, click the CPT (Classroom Presentation Tool) tab on the left-hand side. You will find the online version as well as the different desktop apps to use your CPT offline, without an internet connection.
