She has been teaching for a long time, and has a third grader to type up her lessons for her. Her purpose was to introduce shapes and make designs. She cut down on some of the activity by cutting out the shapes herself. We formed groups to arrange patterns on paper.
Students can use a tape measure or ruler to measure the perimeter.
They should estimate the perimeter and area before finding them, and their estimates needn't be too accurate. You can use the various shapes to make bar graphs, to display measurements of perimeters and areas. Triangles can be used to re-enforce addition and subtraction facts. Squares can be folded to make triangles. One can estimate how many little cubes fit inside a big cube, and then put them in to determine the answer.
