Imagine you have a basket full of colourful
marbles. You want to find out how many
marbles are in the basket. You see that there
are 4 rows of marbles, with each row
containing 5 marbles:

Imagine you have a basket full of colourful
marbles. You want to find out how many
marbles are in the basket. You see that there
are 4 rows of marbles, with each row
containing 5 marbles:
UNDERSTANDING MULTIPLICATION
Instead of counting each row
individually, you can use
multiplication to find the total
number of marbles. Multiply the
number of rows (4) by the
number of marbles in each row
(5): 4 × 5, which equals 20.

TABLES
Multiplication is not just about memorizing numbers—it’s
also about spotting patterns.
Let’s take the 5-times table as an example:
1 × 5 = 5
2 × 5 = 10
3 × 5 = 15
4 × 5 = 20
5 × 5 = 25
What patterns do you see?
The last digits keep repeating: 5, 0, 5, 0, 5, 0…
All the answers end in either 0 or 5.

Now, can you guess the last digits of 11 × 5
and 12 × 5?
11 × 5 = 55 ? ends in 5
12 × 5 = 60 ? ends in 0

By noticing patterns, we can predict
answers without fully calculating. This
makes multiplication easier and more
logical.
