Most teachers that use Freckle don't have a class set of devices. Truthfully, all you need is a few iPads, Chromebooks, computers or any of our other supported devices. If you don't have a class set, you can set up a Freckle center, and then have the students rotate through it to complete their work.
Once your students have completed the diagnostic test, you can use the printables tab to get tailored printable practice for each student. As you continue to rotate your students through centers, you can always generate new printables that automatically adjust to the student's level.
