Opening Out

The author of this article uses four NRICH investigations to illustrate how a teacher might extend the results of students' work as a springboard for developing deeper mathematical understanding. He models good prompting, e.g., "Tell me what you notice about the result" and "I wonder what would happen if ...", and warns against trying to lead students' thinking. [The problems discussed are cataloged separately.]

This resource is included in the following PD Collection(s):
CCSS Practice Standard 7This collection supports teachers as they integrate Practice Standard 7 into their classroom routines. In these articles and videos, teachers will see strategies that help guide students to look for and make use of structure as they discover and understand mathematical concepts. Additional resources for immediate use in the classroom can be found in a companion classroom collection.
CCSS Practice Standard 8The resources in this collection are intended to help educators understand and implement the eighth Mathematical Practice Standard of the CCSS. You will find informative presentations, lesson plans, and problem sets that will help establish mathematical habits of mind that support this standard. You'll also find many problem tasks for use with students in the companion classroom collection.

      A mathematical approach
      By Uncle Bob on 03/03/2013 - 11:34
    • Good examples that would help a teacher develop mathematical thinking in students. One good Q/A should lead to at least two more good Q. Developing the "what do you notice" habit is worth the time.
