Navigate to your course website.  Make sure editing is turned on by clicking the Edit mode toggle in the upper-right corner of your screen.  

1. Click the Block drawer tab in the upper ride side of your screen to open the Block drawer.  
2. Click the Add a block button.
3. From the menu that appears, click Sharing Cart.

1. To the right of the item you want to copy, click the Sharing Cart icon
2. When you see the confirmation message, click Confirm
3. The item will now appear in your sharing cart

Next to each item in your sharing cart, you'll find four icons.  The first three of these are used to manage the items in your sharing cart.

1. Move the selected item to a folder.  When you click this icon, you'll be prompted to name a folder and, when you're finished, the item will be placed in that folder.  Note that this folder only exists in your sharing cart; the folder you define there is not connected to any folder in any of your courses.
2. Move the item up or down in your sharing cart list.
3. Remove the item from your sharing cart.  This option does not delete the item from your course.

Navigate to another course where you have the teacher role and turn editing on using the button in the upper-right corner of your screen.  You'll see the Sharing Cart block on the left side of your screen in the same position as in the first course.  If you don't see the Sharing Cart block, add it to this course following the directions in Step 1, above.  The contents of your sharing cart in this course will be the same as the first course.

To copy an item from your sharing cart to this course:

1. Click the Copy to course icon next to the item you want to copy
2. In each section of your course you'll see placeholders.  Click on one of them and the item will be copied to the bottom of that section.
