Solving Word Problems
Part Two
To solve some
word problems,
you must use
multiplication
or division.
In order to
know which
one to use,
look for the
CLUES.
Multiplication Clue
Most multiplication problems
will ask you to find “how many”
there are “in all,” or
“altogether.”
For example…
Brian has 5 apple trees in his
backyard. Each tree has 10 apples on
it. How many apples are there in all?
Do you see the multiplication clue?
If you said…
“How many” apples are there “in
all,” then…
You’re right!
Division Clue
Most division problems will ask you
to find “how many” there are in
“each.”
For example…
Ann planted 30 cabbage plants in her
garden. She planted them in 3 equal
rows. How many plants did she plant
in each row?
Do you see the division clue?
If you said…
“How many” did she plant in “each”
row, then…
You’re right!
Now that you know the
clues…
