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.
