Here’s a shareable free web based white board- Web Whiteboard!. Use it to pose a question and have students respond (in this way it is similar to Padlet). But you can also draw. The free account will allow you to create 21 day boards and then share with the url. You could put it in Google classroom or perhaps use a QR code. Students could work together on problems or webs.
