Most districts today focus their remediation efforts on their lowest achieving students. Fill allows you to remediate every student, every time they don't master a lesson. Even students who achieve averages of 90% fail to master 10% of their lessons each year. Not anymore. With Fill, you track every student on every math lesson in 2 minutes a day using your warm-up problems. With the click of a button, Fill interfaces with your school's schedule to automatically place students who need more help into remediation classes that fit into their schedules every day. This means that each day, your remediation class' roster is different based on the exact students who still need to master the lesson.
