Exploring Perimeter is a complete resource for teaching perimeter concepts. It's organized in sequential order according to skill level to make it easy to teach for deep understanding. Skills range from learning to count around a shape to hands-on strategies for finding formulas. Click the chart below to see a list of all skills and their corresponding Common Core Standards.
When you develop these concepts in a step-by-step manner, students are far more likely to grasp those concepts and retain them.
