Many students struggle with Executive Functioning. According to WebMD, "Executive Function is a set of mental skills that help you get things done. These skills are controlled by an area of the brain called the frontal lobe. Executive function helps you: Manage time. Pay attention."
One option for helping students that struggle with managing time or paying attention is My Homework Reminder.
My Homework Reminder is an extension that provides a simple way for students and teachers to create reminders and to-do lists from within the Chrome browser. Because it is a Google Extension, users can quickly add items, create due-dates, and view completed assignments without having to disrupt what they are currently working on.
