Comment
1. This is a daily activity that helps children understand the monthly and yearly calendar, large numbers, place value, money, and number sentences (equations/algebra).
2. This video was filmed on day 165 of the school year so the children are quite good at the activity.
3. Detailed instructions for conducting this activity can be found in the book, Math: Their Way.

Study Questions
1. How does the teacher start the activity?
2. Why does the teacher use, “Is there another way?” questions?
3. Describe the verbal/non-verbal management techniques used by the teacher.
4. What math operations do the children practice in the activity?
5. Some of the children try to “Stump the teacher.” Is this effort extemporaneous?
