How can I post explanations of courses and content I have assigned?
Edited
Log into tynker.com as a teacher.
Click on one of your class cards.
Click the Stream button in the top right of the screen.
Click the text box at the bottom of the chat for message options.
Type the message you want to send while attaching both links and Tynker lessons to the post.
Students can then access the post from the Stream in their class dashboard and add comments and questions.
