Theme Spark is a great resource for teachers. It generates rubrics for any grade level and any topic.
At my school, our staff was having a challenging time creating rubrics for collaboration and presentation; especially at the kinder and first grade level. Theme Spark not only has rubrics for those but you can change them to be measure grade levels and/or proficiency levels. For any teacher or administrator leading a PLC I highly recommend ThemeSpark. This is a great tool that can help guide conversations within a PLC.
