WRITING
SUBTRACTION
NUMBER
SENTENCES
The story is about the three candies
left in the jar after two candies are
taken away from five candies. The
story can be stated using subtraction
number sentence 5 – 2 = 3. We can
read this subtraction number
sentence as “five minus two equals
three”.
Ask:
What does 5
represent?
Ask:
What does 2
represent?
Ask:
What does 3
represent?
Good Job!
We do subtraction to know how
many objects are left when we
take away some objects from a
set of objects. It is also possible to
use subtraction to know how
many objects are taken away
from a set.
To get 3, 2 was subtracted from 5
or 5 – 2 = 3. The minus sign (-), tells
us to subtract a number from
another number. The equal sign (=)
tells us that 5 - 2 has the same
value as or equal to 3.
In the subtraction number
sentence, 5 – 2 = 3, 5 is the
minuend, 2 is the
subtrahend, and 3 is the
difference.
Direction: Let us have another story.
___ books are on a table
___ books are taken away
___ books are left on the table
This can be written in
subtraction number
sentence as
7 – 3 = 4.
Ask:
What each
number in the
subtraction
sentence tells us?
Good Job!
In the subtraction sentence 7 – 3 =
4, 7, the number of books before
taking away anything, is the
minuend; 3, the number of books
taken away is the subtrahend; and
4 the number of books left, is the
difference.
Direction: Let us have the last story.
___ pencils are in a box
___ pencil is taken away
___ pencils are left in the box
This can be written in
subtraction number
sentence as
9 – 1 = 8.
Ask:
What each
number in the
subtraction
sentence
represents?
Good Job!
• Nine, the number of pencils in
the box, is the minuend.
• One, the number of pencils taken
away, is the subtrahend.
• Eight, the number of pencils left
in the box, is the difference.
Ask:
What is a
minuend?
Ask:
What is a
subtrahend?
Ask:
What is the
difference?
Good Job!
Direction: I will post the result of the
activities on the 3 stories that you had
done the previous day.
Story 1:
4 tricycles are in a terminal
1 tricycle left the terminal
3 tricycles remained in the terminal
Story 2:
10 balloons are held by a man
5 balloons popped
5 balloons are left
Story 3:
6 birds are on a branch
4 birds flew from the branch
2 birds stayed on the branch

number sentences.
4. Ask the learners to identify the minuend, subtrahend,
and difference in each number sentence.cc
