    Students work in groups of four: A Viewer, A Recorder & 2 Measurers {shadow diagram.jpg}
    You will need 100' measuring tapes, a calculator, and tall objects to measure.
    ...
    try this.
    1.) The viewer stands a little away from the object in question.
    2.) The measurers measure the length of the viewer's shadow(V).
    ...
    7.) The measurers measure the distance from the mirror to the object in question.
    8.) The recorder writes the measurement as w.

    With TRIG -
    When teaching geometry and doing the chapter on trig, students would encounter problems with a triangle, one side and one angle given, {Indirect Measurement.png} and they had to find another side, often the height of a building or tree. What I found is that they could do it in the book but when I took them outside, the "question in the book" became a real "problem" real with real challenges and required them to think more deeply into what they had to do.
