We are finalizing our rubrics for star ratings and recommendations from the Lesson Hive team. Here is more information about how we rate resources and criteria for inclusion with the "recommended" label. When we find a resource that our reviewers rank at 2 stars or lower, we delete it from the database. We use a separate rubric for supplemental resources -- videos, coloring pages, and readings for example. These can help expand a lesson to become more 3 dimensional.
