Title: USING LAYOUT TOOLS

1
USING LAYOUT TOOLS
• Sweet Springs R-7

2
System of Measurement
• English standard measurement in the United
States, now called U.S. Customary System
• Uses, inch, foot, yard, rod and mile as units
• 12 inches in a foot
• 3 feet in a yard
• 16 ½ feet in a rod
• 5,280 foot in a mile

3
System of Measurement
• Metric System used for scientific work in the
United States
• Measurements are based on the meter
• 1 Meter 100 centimeters (cm)
• 1 Meter 1,000 millimeters (mm)
• 1000 Meters a Kilometer (km)
• Units are in multiples of 10

4
Inch as a Unit of Measurement
• Traditional unit for woodworking and metalworking
• Some fine rules or scales have 32 marks per inch.
• Most rules have 16 marks per inch with each mark
equaling 1/16 of an inch.

5
(No Transcript)
6
• Identify how many marks there are to an inch.
• Measure item and count how many marks past a
whole number.
• Reduce to least common denominator

7
• How many marks are there to an inch on this
ruler?
• 16

8
• Locate the marks for 1, 2, 3 and 4
• Inch marks are the longest, usually the number is
located under or to one side of the line.

9
• Look at the lengths of the lines to determine
measurement.
• The longest line is for a whole number 1
• Next longest line is for 1 /2
• Next longest line is for 1 / 4 and 3 / 4
• Next longest line is for 1 / 8, 3 / 8, 5 / 8 and
7 / 8
• Remaining lines are 1/16, 3/16, 5/16, 7/16, 9/19,
11/16, 13/16, 15/16

10
• On the strip of paper given to you, write 0 on
one end and 1 on the other.
• Fold in half and draw line on the crease, write 1
/ 2 at the crease.
• Fold in half again. The creases created are 1 /
4 and 3 /4
• Fold in half again to get 1, 3, 5, 7 /8th
• Fold in half again to get 1,3,5,7,9,11,13,15,
16ths

11
• The Letter A represents what measurement?
• 1

12
• The Letter B represents what measurement?
• 1 7/16

13
• The Letter C represents what measurement?
• 1 14/16 or 1 7/8

14
• The Letter D represents what measurement?
• 2 11/16

15
• The Letter E represents what measurement?
• 3 1/16

16
• The Letter F represents what measurement?
• 3 5/16

18
Working With Fractions
• What is a fraction?
• It is a portion of a whole
• They have a numerator (Top Number)
• And a denominator (Bottom Number)
• 1 / 2 would mean 1 part of 2

20
• With common (same) denominators
• Denominators stay the same
• ¼ ¾ 4/4
• 3/8 5/8 8/8
• 3/16 7/16 10/16

21
• 1 / 4 1 / 4
• 2 / 4
• 3 / 4 3 / 4
• 6 / 4
• 1 / 8 3 / 8
• 4 / 8
• 5 / 8 7 / 8
• 12 / 8
• 1 / 8 5 / 8
• 6 / 8
• 3 / 16 3 / 16
• 6 / 16
• 1 / 16 5 / 16
• 6 / 16
• 7 / 16 5 / 16
• 12 / 16

22
• Add Fractions With Like Denominators using Circles

23
• With uncommon (different) denominators
• One or both fractions will need to changed so
both will have a common denominator
• 3/8 3/16
• First change 3/8 to 6/16 by multiplying both the
numerator and denominator by 2
• 6/16 3/16 9/16

24
• 1 / 2 1 / 4
• 3 / 4
• 1 / 2 1 / 8
• 5 / 8
• 1 / 2 1 / 16
• 9 / 16
• 1 / 4 1 / 8
• 3 / 8
• 1 / 4 1 / 16
• 5 / 16
• 1 / 8 1 / 16
• 3 / 16
• 3 / 16 1 / 2
• 11 / 16
• 5 / 16 3 / 8
• 11 / 16

26
Reducing Fractions
• Reduce fractions to their least common
denominator.
• Divide the numerator and denominator by the same
number so both are whole numbers.
• 4 / 8 1 / 2 (both 4 8 can be divide by 2)
• 5 / 8 5 / 8 (cannot be divide and remain a
whole number)
