Laura Candler, a retired elementary teacher with 30 years of classroom experience, operates the Teaching Resources website (lauracandler.com) where she offers free educational materials to teachers. Candler has authored over 100 ebooks and 7 published books, and has received recognition including the Milken Family Foundation award and National Board Certification as a Middle Childhood Generalist.

Candler's website features an online "File Cabinet" containing free printables and lessons that she created for her classroom and now shares with others. Educators can sign up for her free email newsletter, "Candler's Classroom Connections," to receive notifications about new free resources added to the file cabinet.

One of Candler's educational resources is "Mystery Perimeters," a teaching tool designed to help students find the lengths of unlabeled sides of an irregular polygon to calculate its total perimeter. The resource includes two versions: one using customary measurement (inches) and another using metric measurement (centimeters). It is aligned with 3rd grade measurement and geometry standards and can also serve as a review for grades 4 and 5, particularly for students who benefit from concrete, hands-on lessons.

"Mystery Perimeters" is an expanded version of a lesson found in Candler's comprehensive resource "Exploring Perimeter," which contains over 60 pages of ready-to-use printables, step-by-step lessons, and hands-on activities for grades 2 through 4. Both resources are part of Candler's Geometry Explorations, which includes several other educational products such as "Geometry: Exploring the Basics," "Amazing Angles," "Polygon Explorations," and "Polygon Sorting for Google Classroom."

Candler's teaching approach emphasizes interactive strategies and hands-on learning. She believes in teaching students to accept responsibility for their own behavior and learning, and she is passionate about using the Reading Workshop approach to share the joy of reading with children.
