This is a slides lesson on Area & Perimeter of squares and rectangles.  Students will use formula sheet to find the area and perimeter of squares and rectangles.

Students develop and solidify their understanding of the concept of "perimeter" as they engage in a portion of the civil engineering task of land surveying. Specifically, they measure and calculate the perimeter of a fenced in area of "farmland," and see that this length is equivalent to the minimum required length of a fence to enclose it. Doing this for variously shaped areas confirms that the perimeter is the minimal length of fence required to enclose those shapes. Then students use the technology of a LEGO MINDSTORMS(TM) NXT robot to automate this task. After measuring the perimeter (and thus required fence length) of the "farmland," students see the NXT robot travel around this length, just as a surveyor might travel around an area during the course of surveying land or measuring for fence materials. While practicing their problem solving and measurement skills, students learn and reinforce their scientific and geometric vocabulary.

This learning resource provides students insight into combining and subdividing figures as well as utilizing the understanding of quadrilaterals.  Along with the exploration, students will be developing critical thinking through the decisions that are made to create the final mathematical product.  They will also communicate through collaboration to produce a final mathematical product.  They will also develop creative thinking and citizenship by producing a written piece to show their caring and understanding nature.
