Fractions of an Inch By Miss O.

2
Measuring to the nearest fraction of an inch. What is between a 1 inch and a 2 inch on a ruler? What do all the tick marks represent?

3
The tick marks represent fractions! Fractions are between each inch on a ruler. Using fractions of an inch makes your measuring more EXACT.

4
“Benchmark” Fractions You Have to MEMORIZE! How long is the length of the arrow to the nearest inch? Benchmark means “standard.”

5
Fractions of an Inch Song (to the tune of “Here We Go Round the Mulberry Bush”) Tap your tip on a half of an inch, Half of an inch, half of an inch. Tap your tip on a half of an inch; There’s 2 in every inch! 0 1 =

6
Fractions of an Inch Song Verse 2 Tap your tip on a quarter of an inch, Quarter of an inch, quarter of an inch. Tap your tip on a quarter of an inch; There’s 4 in every inch! 0 1 = =2 24

7
Fractions of an Inch Song Verse 3 Tap your tip on a eighth of an inch, Eighth of an inch, eighth of an inch. Tap your tip on a eighth of an inch; There’s 8 in every inch! 0 1 = =

8
A Poem to Help Us Memorize Start with one eighth, then one fourth, Next three-eighths, and half of course! After that comes five-eighths, Three-fourths, seven-eighths—wow, we’re great!

9
Finding Fractions of An Inch Worksheet yellow Trace each inch mark in yellow. orange Trace each half-inch (1/2) mark in orange. red Trace each quarter-inch (1/4) mark in red. blue Trace each eighth-inch (1/8) mark in blue. green Trace each sixteenth-inch (1/16) mark in green.

10
What if the marks are NOT labeled? Like on MOST rulers… That’s why you have them MEMORIZED… – So…you can write them in yourself and still be able to measure to a fraction of an inch!

11
Let’s practice! 0 1 How long is the length of the arrow to the nearest fraction of an inch? inches Share your answer with a partner!

12
Let’s keep practicing! 0 1 How long is the length of the arrow to the nearest fraction of an inch? inches Write your answer in your math notebook.

13
And some more! 0 1 How long is the length of the arrow to the nearest fraction of an inch? inches Write your answer in your math notebook.

14
Read the directions carefully! 0 1 If the directions say “measure to the nearest inch,” you have 1 option the whole number inch! inches Nearest Inch Whole number inches only!

15
Read the directions carefully! 0 1 If the directions say “measure to the nearest half inch,” you have 2 options the whole number inch or the ½ inch between! inches 1/2 Nearest Half Inch Whole number inch ½ inch

16
0 1 If the directions say “measure to the nearest quarter inch,” you have 4 options the whole number inch, the ½ inch, or the quarter inches (1/4 and ¾)! inches 1/2 1/4 3/4 Quarter of an Inch Whole number inch ½ inch ¼ or ¾ inch

17
0 1 If the directions say “measure to the nearest eighth of an inch,” you have 8 options the whole number inch, the ½ inch, the quarter inches (1/4 and ¾), or the eighth inches (1/8, 3/8, 5/8, and 7/8)! inches 1/2 1/4 3/4 1/8 3/8 5/87/8 Nearest eighth of an Inch 1 whole inch ½ inch ¼ or ¾ inch 1/8, 3/8, 5/8, 7/8 inch

18
Read the directions and then measure! 0 1 Measure to the nearest whole inch. inches Write your answer in your math notebook.

19
Read the directions and then measure! 0 1 Measure to the nearest half inch. inches Write your answer in your math notebook.

20
Read the directions and then measure! 0 1 Measure to the nearest quarter inch. inches Write your answer in your math notebook.

21
Read the directions and then measure! 0 1 Measure to the nearest eighth inch. inches Write your answer in your math notebook.

22
Read the directions and then measure! 2 3 Measure to the nearest eighth inch. inches Write your answer in your math notebook.

23
Read the directions and then measure! 2 3 Measure to the nearest half inch. inches Write your answer in your math notebook.

24
Estimating Fractional Parts Estimating means “guesstimating.” Using the “benchmark fractions” we have been learning with measuring the nearest inch, we can “guesstimate” fractional parts too!
