MULTIPLICATION3x8: ?

What does it mean?

Multiplication meansthat you have a certain number of groups of the same size.

How can you express the same quantity using numbers?

Now, identify its parts:

3 X 2 : 6

Factors : Product(Multiplier and multiplicand) : Product

How do you read it?

3 X 2 : 6

Three times two equals six

Practice

a) Completeb) Identify the parts of the multiplication c) Write each operation.

4X3: _____. 5x6: ______. 7x1: ______. 9x3: ______. 8x5: ______.

How did you solve the previous

multiplications?- Did you use images?- Did you use time tables?- Did you addition?- Did you use your fingers to count ?

There are different ways to solve a multiplication

1. Repeated Addition: The basic idea of multiplication is repeated addition.

For example:

5 × 3 = 15 or 3+3+3+3+3= 15

What is it?It is when you add the same number again and again in order to find

the answer to a multiplication.

Example:Here we have five groups, and each group has two elephants.

5 × 2 = 10

how manygroups?

how manyin each group?

We can solveit by

adding:

5 × 2    =    2 + 2 + 2 + 2 + 2 =

10

Five times two elephants is ten

elephants.

Remember that you need to use

the same numbers of the

operation.
