Why, hello there!
What a pleasure it is to make your acquaintance. I'd like to introduce you to a little packet that has helped my students become more proficient at engaging in conversations.
There's an anchor chart that lists various sentence stems to get them started. Plus there are two strategies for increasing interaction between your students. The Discussion Roundtable has each member of a team giving their response as the other members take notes in order to summarize what they think at the end. The Literal Conversation sheet has them writing responses and swapping with a partner to write down their reactions.
I hope you find them useful in your classroom as your students grow to become more engaging conversationalists. Thank you for your time. Have a wonderful day.
