Complete the Pre-Course survey found below.
In preparation for the first session, read the introduction to the Building a System of Tens Casebook. Then read chapter 1, “Students’ addition and subtraction strategies,” including both the introductory text and cases 1 through 5. Use the questions posed in the introduction to the chapter to guide your reading.
You may encounter ideas that are new to you as you read, particularly when you read cases written by teachers of grade levels you do not teach. Take notes as you read to prepare for the discussions. Remember, the reading is in preparation for a course session in which you will have a chance to explore the mathematics involved in these cases.
If you have not, now would be a great time to order your casebook. Chapter 1 is the only chapter provided digitally.
