Fun with Multiplication


C) Tricks with your age.

Write your age_____________

Multiply it by 7 ___________

Again multiply the answer by 13 __________

Multiply again that answer by 11 __________

Now look at your last answer. Can you find your age in that answer? How many times does your age show in the answer?

Now try this trick with other people.



Dolma took a loan from a friend to buy a moped for Rs 9,588. She has to pay it back in equal amounts every month for six months.

  • How much will she have to pay every month? She asked her children to calculate.

Will both of them get the same answer? Discuss.

Practice time

Try to solve these using as few steps as you can.

Giving children the opportunity to find and discuss the errors in these examples will help their own understanding about the different steps for division. In A) a very common error has been given in which children either forget or do not understand the remainder. In B) there is a simple error of multiplication but there is also a more interesting question of whether the child has shown one extra bus for one remaining child.
