Do You Know What the Following Mean?

• The CUBIT
• The Fathom
• The Hand/span
• The Pace
• The Girth
• The Palm

The Cubit

• Was the measurement used by the Egyptians to
  build the pyramids.

• The cubit was defined as the measurement from
  your elbow to the tip of your middle finger when
  your arm is extended.

5
The Fathom

• Used by seaman. For the most part it was used to
  measure the depth of water so that boats would
  not run aground and people would be stranded.

• The fathom is the measure from fingertip to
  fingertip when your arms are stretched sideways
  as far as they will go. You sometimes see a rope
  and thread measured this way.

6
The hand-span

• Was used to measure the height of horses. You
  still hear of people saying about horses being so
  many hands high.

• The hand-span is the measure from the tip of your
  pinky to the tip of your thumb when your hand is
  stretched out.

7
The Pace

• This term was used by the Roman army to judge
  speed. The term is still used quite frequently
  during various types of foot races.

• The pace is the distance from one step to
  another. Just like walking or running the
  distance from one step to another.

8
The Girth

• One use for this type of measurement was in
  measuring fishing line

• The girth was the measurement around ones
  stomach (your belt measure).

The Palm

• The palm was the width found by placing your 4
  fingers together.

10
Some folks found measuring in this fashion to be
quite challenging.
11
The Cubit

• Who said 3 heads are better than one? For these
  ladies it proved to be a team event.
• Can anyone see anything wrong with this
  technique???

12
The Fathom

• Not a bad way to do this exercise. I hope that
  their arm lengths were the same length???
• Good Teamwork!

13
The Hand-Span

• Working as a team these two girls kept track of
  their research in case one forgot what number
  they were on.
• Good planning!!!

14
The Pace

• Now this was a BLAST to see how some people
  interpreted this function.
• Pay attention to the following examples

Mr. Obvious
15
Hey, how tall am I?

• He asked how many paces tall I was, not how many
  feet.

16
Pacing can be a PANE of glass, that is!

• Ok when Im done helping you you help me
  OK!!!

17
Pacing the Door

• His calculations may be off a little, but I bet
  he got an A in Phys.Ed.

18
Had enough? Oops Palming

• Life can be frustrating.
• To be successful you have to step back and look
  at your choices and then choose your options.

19
Table Palming

• Well, at least this part of the exercise was
  clean and easy.

A Hands-On Activity

• Ok you start on that end and Ill start on this
  end and well meet in the middle.
• Oops! I forgot where I was guess I gotta
  start over.

22
Ever wonder how engineers would do it?

1. They would count the tiles and/or blocks and use
   them as a reference.
2. They could use these items to calculate how many
   would make one of each unit.
3. Then they would multiple their results.
4. LASTLY, they would be the cleanest people doing
   the activity because they used their BRAINS and
   not their brawn!!! Thats why they make the big
   .

Well how did you do?

• Would you like to work smarter and not harder?
• Would you like a career where you can stay clean
  and make mucho bucks?

  draw, or make stuff or wonder how the world
  works?
