Welcome to Jigsaw University 101! Above you will find a picture of the 5 diversified assets that have been added to my asset library as well as the unique tags for each asset. To demonstrate that I have used one of these assets in a session I have created this quick clip https://stream.jigsawme.com/u/0qGbF4.
It is definitely a best practice to create and add assets prior to your synchronous sessions because it helps the flow of the class to be better and minimizes connectivity glitches. For example, if you upload the audios to the assets prior to class, the audio will play clearly as opposed to forgetting to add the audio, trying to play it from your computer and hoping your microphone will pick up the sound so the students can hear it.
