What is Perimeter

When teaching elementary children remotely, it is imperative that they are provided with an opportunity to thoughtfully evaluate mathematical concepts. Learning must go beyond rote memorization and the recalling of information. Rather, there needs to be a focus on discovery of connections and concepts. The focus of this chapter is guiding students to discover features of shapes using tools and technology through remote instruction with an emphasis on problem posing. Activities are provided to help intermediate elementary students explore the impact that doubling or tripling dimensions has on perimeter and area for two-dimensional shapes and surface area and volume for three-dimensional shapes. Activities that increase in difficulty as well as extensions are provided to differentiate instruction. Lessons are designed to use technology to promote discovery of mathematical relationships using technology. Strategies for remote lesson plan design in mathematics are provided.
