Let’s try division
!
How do we use models to solve
word problems?
Let me show you how.
Here’s an example.
Question:
A pole is 16 m long.
It is cut into 2 equal parts.
What is the length of each part?
Let’s assume the bar below
represents the length of the pole.

16 m
Question:
A pole is 16 m long.
It is cut into 2 equal parts.
What is the length of each part?
Since the pole is cut into 2 equal parts,
we need to divide the bar into half.
16 m
Question:
A pole is 16 m long.
It is cut into 2 equal parts.
What is the length of each part?
Each part should be similar in
size.16 m

Question:
A pole is 16 m long.
It is cut into 2 equal parts.
What is the length of each part?16 m

16 ÷ 2 = 8
Question:
A pole is 16 m long.
It is cut into 2 equal parts.
What is the length of each part?16 m
?
Ans: 8 m
÷ is the symbol to show ‘divide’.
If we put 10 apples into 5
baskets,
we can write 10 ÷ 5 to show the
steps.
