A scale and rubric for each of the 3rd grade Geometry standards. Perfect for students to self-monitor their learning and for teachers to use for data collection in large or small groups. Each standard comes with "I can statements" and a 1-4 proficiency scale for students to determine what level they are working at and what they need to do to improve. Students also have space to write their levels and to justify why they rated themselves there! Fits perfectly with Marzano scales!
