1 LEARN THE RULER FRACTIONS OF 4 TH, 8 TH, & 16 TH Different types of rulers

2 Why Learn to Read a Ruler? Reading a ruler is a valuable skill that you will likely use on your job, in your hobbies, and in your personal every day life. Without measuring devices like rulers, and people that can read them, we would still be living in caves

3 TYPICAL UNITS IN A RULER 1.0 INCHES – FRACTIONS – DECIMALS 2.0 METRIC CM-centimeter MM-Millimeter

4 UNITS OF THE RULER TOP SECTION IS IN INCHES BOTTOM SECTION IS IN CENTIMETER- PART OF THE METRIC SYSTEM OR UNIT

5 ON THIS PRESENTAION WE ARE LEARNING –INCHES AND FRACTIONS ALL FRACTIONS ARE IN INCHES SAMPLES A.1.0 INCH B.1 ½ INCHES (IS MORE THAN ONE INCH) C. 5/8 OF AN INCH (IS LESS THAN AN INCH) B. ( 1 ½ ) A. ( 1.000) C. (5/8)

6 STEPS ON HOW TO READ A RULER STEP 1 *FROM ZERO TO ONE CAN BE CUT IN HALF *THE LINE IN THE MIDDLE IS 1/2 1/2 ZERO LINE

7 STEP 2 *CUT FROM ZERO TO ½ IN HALF AND FROM ½ TO IN ½ AND YOU GET A TOTAL OF FOUR LINES. *NOTES: (YOU NEVER COUNT THE ZERO LINE) 1/2 ZERO LINE 1/4 2/4 3/4 4/4 FIRST LINE SECOND LINE THIRD LINE FOURTH LINE IF YOU NOTICE THE LINES WITH FRACTIONS, THE BOTTOM NUMBER IS ALWAYS FOUR BECAUSE THERE IS A TOTAL OF FOUR LINES AFTER THE ZERO LINE, 2/4 IS REDUCED TO ½ AND 4/4 IS EQUAL INCH

8 STEP 3 *NOW LETS CUT THE FOUR SPACES IN THE PICTURE BELOW IN HALF AND YOU GET A TOTAL OF EIGHT LINES. *NOW THE FRACTIONS WILL BE IN 8THS 1/2 ZERO LINE 1/4 2/4 3/4 4/4 IF YOU NOTICE THE FRACTIONS IN GREEN, THE BOTTOM NUMBER IS 8, BECAUSE THERE IS A TOTAL OF 8 LINES 1/8 2/8 3/8 4/8 5/8 6/8 7/8 8/8

9 STEP 4 *NOW LETS CUT THE EIGHT SPACES IN HALF AND WE GET A TOTAL OF 16 TH LINES 1/2 ZERO LINE 1/4 2/4 3/4 4/4 IF YOU NOTICE THE FRACTIONS IN GREEN, THE BOTTOM NUMBER IS 8, BECAUSE THERE IS A TOTAL OF 8 LINES 1/8 2/8 3/8 4/8 5/8 6/8 7/8 8/8 1/16 2/16 3/16 4/16 5/16 6/16 7/16 8/16 9/16 10/16 11/16 12/16 13/16 14/16 15/16 16/16
