BEGINNING MULTIPLICATION

BASIC FACTS 0 - 4

Multiplication is

REPEATED ADDITION.

It is a shortcut to skip counting.

The first number in the problem tells you

how many sets you have.

The second number tells you how many

elements or objects are in each set.

In the problem

2 X 3

The 2 shows you that you have 2 sets.

The 3 tells you that there are

3 elements or objects in each set.

If you have 2 sets with 3 elements or objects

in each set you will have a total of

6 objects or elements.

SO…

2 X 3 = 6

Let’s try some.

1 X 2

1 set

2 elements in the set

1 X 2

3 X 1

3 sets

1 element

in each set

3 x 1

1 X 0

There are NO elements

In this set!

This set isEMPTY!

ZERO ELEMENTS

0

0 X 4

There is NO

set to put elements in.

Zero sets = Zero

0

1 X 3

1 set

3 elements in the set

1 X 3

2 X 2

2 sets

2 elements in each

2 x 2

0 X 1

No set.

No set to put elements in.

Zero times # always = zero

0 x 1

2 X 1

2 x 1

3 X 2

4 X 0

4 empty sets

0 X 0

Zero sets

Zero elements

2 X 4

1 X 1

0 X 3

3 X 4

2 X 0

4 X 2

0 X 2

2 X 3

4 X 4

3 X 0

4 X 1

3 X 3

1 X 4

4 X 3

Now let’s see how manyyou can remember!
