Area and Perimeter Covering and Surrounding

Concept with Explanation
Selected Homework from ACE

In Covering and Surrounding student work with investigations leads them to:

• Understand area and relate area to covering a figure;

• Understand perimeter and relate perimeter to surrounding a figure;

• Develop strategies for finding areas and perimeters of rectangular shapes and non-rectangular shapes;

• Discover relationships between perimeter and area. including that each can vary while the other stays fixed;

• Understand how the areas of simple geometric figures relate to each other (e.g. the area of a parallelogram is twice the area of a triangle with the same base and height);

• Develop formulas and procedures-stated in words and/or symbols-for finding areas and perimeters of rectangles, parallelograms, triangles, and circles;

• Develop techniques for estimating the area and perimeter of an irregular figure; and

• Recognize situations in which measuring perimeter or area will help answer practical questions.
