Cubby
for the last three years,my team has used Planbookedu.com. This next year our school purchased Planbook.com, so I am transferring my plans over. One thing that we agree that we desperately miss from our previous planning site, is that they had a feature called Cubby. This is an AMAZING feature. It acted as a holding spot and allowed you to drag things over and keep util you needed it. Something to research.

Planbook.com now offers a “Lesson Bank” feature! Lesson banks allow you to store away lessons and units, and then add them to your schedule when appropriate. To learn more: https://planbook.uservoice.com/knowledgebase/articles/1193191-lesson-bank
