used for measurement.
Pre-Assessment:
Identify the most realistic
unit of measure for each
of the following:
Pre-Assessment:
Fill in the blanks. Use
as 1 unit of mass.
1. size of your waistline
2. length of Olympic pool
3. distance from Manila to

7. The
_________________ is 3
times heavier than the
banana.
8. The
_________________ is 4
times heavier than the
carrot.
B. Establishing a
purpose for the
lesson
Let the students do the
following and write their
answers on the notebook.
a. Measure the length and
width of your Math book
using your thumb’s width
and the ruler
b. Measure the length of
your classroom using foot
length and meter stick
c.
Compare
your
measurement with those
of your classmate (at least
3)
and
write
your
Estimate first. Record the
object’s estimation, actual
measurement and their
difference on the table
below. Use centimetre
and inch.
Activity A.
Choose the most
appropriate instrument to
use in measuring the
weights of the given
objects. For the weight,
check (√) only one of the
given units.
Determine the dimension
of the following using the
specified metric units only.
Record your results in the
table below and compute
for each objects volume
using the unit used to
measure
the
object’s
dimension. Complete the
table
by
expressing/converting the
volume using specified
units. (For reference, see
observations.

Conversion
Example 1. Convert 60
ounce into pounds
Example:
1. 5.4321 hm = 5432.1 dm
Example 2. Convert 3
2. 0.985 km = 985 m
kg into pounds
Similarly,
move
5
spaces to the left or 5
decimal places to the
left to convert
centimeter to kilometer.
The number of spaces
corresponds
to
the
powers of ten needed to
convert one unit to
another.

Proportions will help you
make conversions when
working with
measurments
Create a unit conversion
ration, which is always
equal to 1:
L, thus move the decimal
point 3 times to the left.
A. For three dimensional
unit, use the metric
converter below.
1. Change 750 mm3 to
cm3
Solution: There is only one
space between the two
units. Thus the decimal
point is moved
3 times to the left.
2. Change 3.48 km3 to m3.
Solution: There are 3
spaces between the two
units. Thus the decimal
point
is
moved
9 times to the
right.
For English Measures
Illustrative Example
1. Convert 1 cubic yard
into 1 cubic feet.
We know that 1 yard = 3
feet
2. Convert the capacity of
30 cubic feet cylindrical
tank into cubic meter.
Example1: How many
yards are in 15 feet?
There are 3 feet in 1 yard,
so the conversion ratio is
Since 1 ft = 0.3048 m,
therefore,
.
Solving algebraically gives
an answer of 5 yards
Example 2: Convert 2
miles into inches
1. What was your reason
for choosing which unit to
use?
2. How did you convert the
metric units of volume (cc
to m3) and vice versa?
3. How did you convert the
English unit of volume?
4. How did you convert the
Metric unit to English unit
of volume and vice versa?
Conversion of English

or vice versa
1 inch = 2.54 cm
3.3 feet = 1 meter
Example: Convert 60

factors which are equal
to 1, only the unit was
