I know I say this all the time but this is one of my favorite sites. Crocodoc allows you to upload any type of document, even PDF, and then, collaboratively edit it. This works fantastic for peer editing. It’s also a great way for you to provide feedback on student work. For example, take pictures of student artwork and load the images to Crocodoc. Then, draw and add comments to the pictures. Send the link to the students’ parents. They’ll love to see their child’s work with comments such as, “Great use of color here!”
A great way to use Crocodoc is when your teaching team needs to work together on a project. For example, your team needs to tweak the curriculum or test questions on a grade-level test.
Below is a sample docment. Feel free to mark it up!
