Learning by Doing
Objective: To learn addition of 4-digit numbers in a play-way method.
Materials required: Paper and pencil
Procedure:
The teacher can take children to the school parking area and tell them
to note down the 4-digit vehicle numbers of any four vehicles. Or she/
he can ask them in advance to note down the vehicle numbers while xy* m7234
they are coming to the school.
Then children will be grouped to work in pairs.
Each child will make four slips and write his numbers. Next each child will take out a
slip and show the number to each other. Then, they will find the sum of the two 4-digit
numbers with the condition that he/she will write his/her own number on the top row.
For example, Child A: 2158 Child B: 4693
So, 2158 4693
+ 4693 + 2158
6851 6851
Check the working of each other and discuss the answers obtained.
Note that the answer should be a 4-digit number. If the answer is a 5-digit number,
it will be ignored and new pair of numbers will be tried.
