The document explains how multiplication and division are related. Multiplication is a shortcut for addition of equal groups, while division is the opposite of multiplication and involves splitting things into equal groups. Examples are provided to illustrate how to use multiplication to solve division problems by thinking of the division sign as asking "what number multiplied by the given number equals the total?"

1. I know how to do
multiplication, but
what about division?
Don’t worry Woody,
it is easy to relate
multiplication and
division.

2. Multiplication is a shortcut for addition.
When you add, you combine amounts.
When you have equal amounts to add, you can
multiply to find the total.

3. Sample
There are 5 bicycles that need new tires.
How many tires is that?
You could add
2+2+2+2+2 to
find the total.
2 2 2 2 2+ + ++
2 + 2 + 2 + 2 + 2 = 10

4. I can also multiply
2 by 5
to find the total.
2 is the number of
tires on each bike.
5 is the number
of bikes.
2 x 5 = 10 Total number of tires

5. is the operation of making equal
groups and finding the number in each group
or the number of groups.
Wow!!!!!!!
That sounds cool!
Division

6. ere are 12 stickers and 3 students. How man
stickers can each student get so that they
each have the same amount?

7. 12 ÷ 3 = 4
Total number of
stickers Total number
of students
Number of stickers for
each student.

8. Sample There are 18 cupcakes. How many cupcakes
can you put into 3 boxes so each
box has the same amount of cupcakes?
18
Total number of cupcakes
÷ 3 =
Total number of boxes
6 Total number of
cupcakes for each box

9. Just like subtraction is the
opposite of addition,
division is the opposite
of multiplication.
u can use what you know about multiplicatio
to help you with division.

10. Multiplication Facts Related Division Facts
4 x 5 = 20 20 ÷ 5 = 4
5 x 4 = 20 20 ÷ 4 = 5
I’ll do
the multiplication
facts.
Ok, I’ll do the
related
division facts

11. Some people find multiplication easier than division.f you do, when you see division, think about multiplication
24 ÷ 8 =
Think:
X 8 = 24
The number you need to write here
is called the missing factor.
= 3
So, you know
AnswerAnswer
because 3 x 8 = 24
24 ÷ 8 = 3
= 3

12. Yeah! We did it!
