Learning goals: Teacher Facing Calculate and compare (orally and in writing) the areas of multiple scaled copies of the same shape. Generalize (orally) that the area of a scaled copy is the product of the area of the original figure and the “square” of the scale factor. Recognize that a two-dimensional attribute, like area, scales at a different rate than one-dimensional attributes, like length and distance.
