Next Steps and Parting Thoughts

1. If you haven't had a chance to try some of the Session 1 Operation Sense tasks with students, why not try them between now and when you work through the next session.

Or perhaps you want to investigate students' thinking about place value and administer the 35 Dinosaurs or 52 and 43 Candies diagnostic tasks.

Either way, for the next session, come prepared to share what you've discovered about student learning and your initial thinking about how you might build understanding.

2. As you help students strengthen their operation sense and move through the operation sense trajectory, explore the role that visual representations and paraphrasing can play, consider the following:

• What evidence can you collect that shows growth in students' ability to use the inverse relationship between addition and subtraction to see connections between the semantic and standard number sentences?
• What did you find to be especially effective in advancing learning?
• Who should you share your findings with?
