English Measuring System Inches, Feet, Yards How many inches in a foot? How many feet in a yard? How many 1/4 inches in an inch? How many 1/8 inches in an inch? Can you figure out the pattern? How many 1/16 inches in an inch? How many 1/32 inches in an inch? 12 inches (0’-12”) 3 Feet (3’-0”) 4 8 16 32

Locate the Ruler Mark Where is 1 3/4 inches? Where is 3 ½ inches?

Read My Line ¾” 1 ¼” 1 5/8” 2 3/8” 2 7/8” 3 ½” 4 1/8”

Read My Line – More Practice Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Read My Line – More Practice A = ¼ in. B = 14/16 = 7/8 in. C = 1 10/16 or 1 5/8 in. D = 2 3/16 in. E = 2 14/16 or 2 7/8 in. Take this opportunity to discuss reducing fractions. This is also a good time to reinforce the denominator based on the length of the line.

Architectural Units – Notation Most architectural drawings use the architectural type of scale displaying measurements in feet and inches, such as 16’-2”.

Convert These Measurements 1 Foot = _______Inches 1 Foot 8 Inches = ______Inches 3 Feet 6 Inches = ________Inches If 4 Blocks = 1 Inch in length, then 3 Inches = _________Blocks 2 ½ Inches = _________Blocks 4 ¾ Inches = _________Blocks 12 20 42 12 10 19

Converting Architectural Units Converting units is a valuable skill that will help you solve many problems and avoid lots of mistakes. The process of converting feet-inches to decimal feet is simple and powerful. You will use this method to calculate area and perimeter in future activities. 7’- 4” = 7’ + 4/12” = 7.333’ 10’-6” = 10’ + 6/12” = 10.5’

Converting Architectural Units Presentation Name Course Name Unit # – Lesson #.# – Lesson Name Converting Architectural Units Students will want to convert 10’-5” to 10.5’. It’s very important to introduce this inconsistency now as we will encounter it throughout the unit. What are the dimensions of Bedroom #3? Convert to Decimal Feet Calculate the Area of this room 10’-5” x 12’-5” 10’+5/12” x 12’+5/12” = 10.417’x12.417’ 129.348 sq ft
