Abstract: A system and methods are disclosed for enabling users to attach a tag and highlight in a single action or activity to a select piece or portion of text in digital content (e.g., in a digital book or other content provided for viewing on an electronic device). In some implementations, the teacher may associate a tag with a particular text in the assignment, push the assignment embedding the tag to one or more students, and the tag becomes automatically visible to the one or more students through their highlight menu when they open up the assignment for completion. In some implementations, with this single activity, users may easily share tasks, comments etc., with ease. One or more other activities are also used among teachers and students to create and execute assignments with efficiency.
