Tables and Graphs

August 27, 2012 Using Tables to organize information

  1. Update your Table of Contents with the date and topic (listed above).

By the end of class, I should be able to:
  • use tables to organize information
  • make comparisons of ratios from information in a table.
  • plot values from a table on the coordinate plane

Assessment

Golden Ratio & our bodies

The golden ratio (symbol is the Greek letter "phi")is a special number approximately equal to 1.618.

Today, you had the task of finding ratios in your body that could possibly contain the golden ratio. We began by comparing the length from your soles (bottom of feet) to the top of your head with the length from your soles to your navel.

An example from Jeremy:
  • Total height (length from soles to top of head): 153 cm
  • Length from soles to navel: 94 cm
  • Ratio → 153 cm / 94 cm = 1.63 (Wow! Getting close)

Find four other ratios on your body that get close to the Golden Ratio.

Homework: On the coordinate plane,

  1. Please make a ratio table that contains the body comparisons in your search for the Golden Ratio
  2. Please graph your data.

  • y-axis: Longer length
  • x-axis: Shorter length
