Measuring in Inches
This is a complete lesson with instruction and exercises for fifth grade. It teaches students about measuring in inches, using the 1/16 parts of an inch.
Here are four rulers that all measure in inches. They are NOT to
scale. Instead, they are magnified to be “bigger” than the actual rulers,
so you can see the divisions better.

1. Find the ½inch mark, 1 ½ inch mark, and 2 ½inch mark on all of
the rulers above.
2. Find the ¼inch mark, the ¾inch mark, the 1
¼inch mark, the 1
¾inch mark, the 2 ¼inch mark,
the 2 ¾inch mark, and the 3
¼inch mark on the bottom three rulers above.
3. On the ruler that measures in
8th parts of an inch, find and label tick marks for these points: the
1/8inch point, the 5/8inch point, the 7/8inch point, the 1 5/8inch
point, and the 2 3/8inch point.
Also, find these same points on the ruler that measures
in 16th parts of an inch.
4. Look at the ruler that measures in 16th parts of an inch. On that ruler find tick marks for these points:



5. Measure the following colored
lines with the rulers given. If the end of the line does not fall exactly
on a tick mark, then read the mark that
is CLOSEST to the end of the line.




















6. Measure the following lines using different rulers. Cut out the rulers from the bottom of this page.
a.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
b.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
c.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
d.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
e.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
f.
Using the 1/4inch ruler: __________ in. Using the 1/8inch ruler: __________ in. Using the 1/16inch ruler: __________ in. 
You may cut out the following rulers:
7. Find six items in your home that you can measure with your ruler and measure them.
a. _________________________ _______ in.  b. _________________________ _______ in. 
c. _________________________ _______ in.  d. _________________________ _______ in. 
e. _________________________ _______ in.  f. _________________________ _______ in. 
8.
Carefully measure the sides of the
quadrilateral at the right, and
find its perimeter.
9. A small rectangular bulletin board
measures 15 3/4 in. by 9 1/8 in.
What is its perimeter?
10. Janet checked the amount of sugar in 10
different cookie recipes. The
amounts were (in cups):
1 1/2 1 3/8 1 1 3/4 1 1/2 1 1/8 1 1/4 1 1/4 1 1/2 3/4
a. Make a line plot from this data
(below) by drawing an Xmark
for each measurement above the number line.
b. If Janet made the recipe with the
least amount of sugar
three times, how much
sugar would she need?
c. If Janet made the recipe with the
largest amount of sugar
three times, how much
sugar would she need?
11. Make a line plot from these measurements (lengths of cockroaches, in inches, in Jake's collection):
1 1/4 1 1/8 1 1/8 1 1/2 1 1 1/8 1 3/8 1 3/4 1 3/8 7/8 1 1/4 2 1/8 1/2 1 1/4 1 1/4
1 1/2 1 1/2 1 1/2 1 5/8
This time, you will need to do the scaling on the number line.
b. What is the mode of this data set?
c. Jake took his five longest cockroaches, and
placed them
endtoend. How long a
“train” did they form?
12. Measure a bunch of pencils to the nearest 1/8 or 1/16 of an inch. Then
make a line plot of
your data.
