The standard states: “Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 7 topics, texts, and issues, building on others’ ideas and expressing their own clearly.”

This standard emphasizes the importance of students being able to actively participate in discussions, both with their peers and with their teacher. They should be able to listen to others’ ideas, build upon them, and express their own thoughts and opinions clearly. This standard helps develop students’ communication and critical thinking skills.
