It represents a pattern of Ls using matchsticks.
Here, we follow the pattern with 1L, 2L, 3L, … and so on.
Continuing in this manner, we can say that the number of matchsticks required is twice the
number of Ls formed.
Matchsticks Pattern of Ls Number of Ls Formed Number of Matchsticks Used
1 2
2 4
3 6
4 8
5 10
6 12
Can you find how many matchsticks are required to form 7Ls and 8 Ls?
We can observe that the number of matchsticks required = 2 × Number of Ls.
So, to make 7 Ls, we require 2 × 7 = 14 matchsticks and to form 8 Ls, we require 2 × 8 = 16 matchsticks.
If we take letter n for the number of Ls, where n can be any natural number 1, 2, 3, …
Then, we can write the number of matchsticks required = 2 × n or 2n
Thus, the above rule gives the number of matchsticks required for forming any number of Ls.
For n = 1, the number of matchsticks required = 2 × 1 = 2
For n = 2, the number of matchsticks required = 2 × 2 = 4
Note: 2 × n is same as 2n.
For n = 3, the number of matchsticks required = 2 × 3 = 6 and so on.
Using the above rule, can you say how many matchsticks are required to form 100 Ls?
create and solve
At what position in the above matchstick pattern (forming Ls), we use the matchstick to form a pattern of Cs?
Make matchstick pattern to form Cs. Complete the table that gives the number of matchsticks required to make
a pattern of Cs.
Number of Cs Formed 1 2 3 4 5 6 7
Number of Matchsticks Used
Discuss and write the rule by using letter n that will give the number of matchsticks required for forming any
number of Cs. Think other letters of the alphabet and other shapes that can be made from matchsticks. Choose
any five and write the rules for making matchstick patterns with them.
