from the current ‘Kentucky Program of Studies’ High School Skills and Concepts – Systems of Measurement Students will -make decisions about units and scales that are appropriate for problem solving situations involving measurement High School Skills and Concepts – Measuring Physical Attributes Students will -describe how change in one or more dimensions of a geometric figure or object affects the perimeter, circumference, area and/or volume of the figure or object

from the new ‘Common Core Standards’ Similarity, Right Triangles and Trigonometry Core Standards · Students understand that: The dilation of a given segment is parallel to the given segment and longer or shorter in the ratio given by the scale factor. A dilation leaves a segment unchanged if and only if the scale factor is 1. Core Standards · Students can and do: Give an informal explanation using successive approximation that a dilation of scale factor r changes the length of a curve by a factor of r and the area of a region by a factor of r 2.

I am learning how a change in one or more dimensions of an object affects the surface area or volume of the object.
