How Many Times?
How many spiders?
One spider has  legs.
In all, spider legs are 3 times 
or  +  +  = 
                   or 3 ×  = 
Do you know this leggy fellow?
This is an octopus.
It lives in the sea.
It also has 8 legs.
So how many legs altogether do 5 octopuses have?
 +  +  +  +  = 
or 5 times  = 
or 5 ×  =

Leggy Animals
There are 5 goats.
How many legs altogether?
4 + 4 + 4 + 4 + 4 = 20
or 5 times 4 is 20
or 5 × 4 = 20

Find the Number without Counting
How many flowers in a flower bed?
It has 4 columns. Each column has 6
flowers. So altogether the flower bed
has 4 times 6 flowers,
6 + 6 + 6 + 6 = 24  or
4 × 6 = 24
Let's try another way. The flower
bed has 6 rows. Each row has 4
flowers. Altogether the flower bed
has 6 times 4 flowers,
4 + 4 + 4 + 4 + 4 + 4 = 24
or 6 × 4 = 24
In the same way, how
many bottles are these?
 times  =  bottles
How many eggs?
 times  =  eggs

Each packet has 4 biscuits. How many
biscuits did Ramu buy?
After children attempt word problems, there should be a discussion on how they arrived at their
answers. This will help children develop a conceptual understanding of multiplication.
