Multiplication On Number Line
Covid19 has led the world to go through a phenomenal transition .
Elearning is the future today.
Stay Home , Stay Safe and keep learning!!!
In multiplication on number line, the students generate the multiplication(product) using a the number line model. Multiplication is repeated addition. This type of multiplication is for small numbers only.Follow the steps:
There are two numbers while doing multiplication.
• Circle the zero.
• 1st number gives you the number of jumps.
• 2nd number given you the step of each jump.
Example 1 : 5 x 3
Here, there are 5 jumps.
Each step is of 2 units.
So the answer is 5 x 2 = 10
_______________________________________________________________
Example 2: 6 x 2
Here frog has taken 6 hops. Each hop is of 2 units.
Jumps = 6.
1 hop = 2 units.
So, the answer is 6 x 2 = 12.

Some examples of multiplication without number line
1) If rabbit has taken 8 hops of 4 then where will he land ?
Solution :
Number of jumps= 8
1 jump = 4
Rabbit will land at 8 x 4 = 32 .

2) If deer has taken 4 hops of 4 then where will he land ?
Solution :
Number of jumps= 4
1 jump = 4
Deer will land at 4 x 4 = 16 .

3) If frog has taken 2 hops of 4 then where will he land ?
Solution :
Number of jumps= 2
1 jump = 4
Rabbit will land at 2 x 4 = 8 .
