Comments: New Math

I am the teacher whose class is featured in this article. The information in the article only represented part of the lesson. What was not included in the article was the class discussion we had about why Leila's method would not be practical. We talked about what would happen if the question was something like 43+98+65. Then it would be extremely time consuming to make tally marks, and as you stated, very prone to error. She then used the associative property to solve the problem as most of the other children did. Thank you for your comments.
