Scurry Labs is a small company that develops helpful web applications for teachers. Two their best products for teachers are called Otter and Sqworl.

Otter is a service that makes it easy to create simple webpages on which you can distribute information and collect assignments from students. Otter provides four widgets that you can add to your page. Those widgets are announcements, calendar events, hosted documents, and homework uploads. The widgets appear in that order on your page. Hosted documents can be uploaded from your computer or imported from Google Drive, Box, and Dropbox. Students can upload their assignment submissions through your Otter page.

Sqworl is a free bookmarking tool for teachers and students. Bookmarks created with Sqworl save a screen capture of each page you bookmark. To help you organize your bookmarks, you can create multiple groups of bookmarks in your Sqworl account. Should you choose to share your bookmarks you can share one or all of your bookmarks groups via the unique URLs that Sqworl assigns to each group. You can add bookmarks to your Sqworl account by manually inputting web addresses or by using a browser bookmarklet. The visual aspect of Sqworl provides a helpful reminder of why a site was bookmarked and what that site is about.
