    So I am trying o think about the continuum of measurement with an upcoming lesson on scaled copies (7th grade).

    Direct Comparison – Looking at the original and copy and determining which is larger.

    Indirect Comparison – Using a line/sting/piece of paper to determine that the height and the width are both larger on the copy.

    Direct measurement – Iterate the original – stacking to see how many times taller and wider

    Indirect measurement – given measurements of the original what is the measurement of the copy (given the scale factor) OR Given the measurements of both the original and the copy, what is the scale factor.
