This is a chart designed to assist teachers in facilitating and supporting scientific discourse between students in their classrooms. The "teacher's back pocket" chart is double sided: one with prompts for teachers, and the other sentence starters for students. The chart is designed to be an instructional tool for a teacher to have in hand or on his/her lap during a student discussion around scientific phenomena or ideas. The tools can be used to help students meet all the Peformance Expectations for Grade 5 Structures and Properties of Matter among others. The presentation used by the creators to introduce the tool and connect it to practices expected in the NGSS can be found here.
