Date: Nov 23, 1998 8:39 AM Author: wendy Subject: Number Sense and Computational Fluency Number sense and computational fluency are major goals of Investigations. Efficiency, accuracy, and flexibility are the key elements of computational fluency. What Investigations activities have helped your students develop number sense and/or computational fluency? Are your students showing an understanding of place value and a facility with number facts? How do we guide students to more efficient strategies when they seem stuck on using inefficient ones? Where do the standard U.S. algorithms come in for an Investigations classroom?
