Let’s say you’ve chosen an engaging lesson to use with your students, and now you’re sitting down to plan your instruction. You know you have a context that will make sense to your students, and you know the questions that arise in that context will be both challenging and productive. You’re hoping to launch the task to engage students with the context and with an understanding of what mathematical question they’ll be answering through their work, then give them time to work collaboratively, and finally bring them together to share strategies, formalize methods, and introduce or refine any relevant vocabulary.
How might you get them started in this context? How might you launch your lesson?
