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 nonrectangular 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 proceduresstated in words and/or symbolsfor 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.
