Perimeter Penny - Engaging Math Center Game for Finding Unknown Sides #2025126 (License: Personal Use)

This vibrant educational resource features a friendly red robot character named Penny, designed to engage elementary students in learning perimeter concepts. The image showcases a sample task card where students calculate the unknown side of a polygon given its total perimeter and other side lengths (e.g., 4 cm, 6 cm, 10 cm, 4 cm, and an unknown side totaling 30 cm). Aligned with Common Core Standard 3.MD.D.8, it supports classroom centers, independent practice, and formative assessment.

Used in elementary math classrooms for grades 3-4 during geometry units; ideal for station rotations, intervention groups, or homework reinforcement. Matches user intent for ready-to-print, standards-based perimeter activities that build conceptual understanding through visual and interactive problem solving.
