Inching Along describes how the development of the concept of area and perimeter, at a basic level, progresses in the primer. It proceeds from the meaning of one small square unit to the implication of how one large region with smaller sections can be measured. Through the use of diagrams and tables, appropriate vocabulary is presented, defined and illustrated. Numerous interactive widgets are included to provide instant reinforcement and repetition, at increasing levels of difficulty. A review section has been included, as well as related activities that are applications of the concept. The primer has a section, comprised of PDF tables and grids, that has been shared.
One inch at a time is sufficient to begin the journey. Many inches away from completing the destination, progress can be made. Inch by inch more depth is added and soon it’s back to square one, only this time, armed with the necessary tools to flourish.
The primer is appropriate for all ages. A basic understanding of English is helpful. However, the images are instructive.
