Maybe you have a shop at school, down the road or somewhere else nearby.
At the end of the day the shopkeeper has to look at the money in the till in order to count it up.

If it were in USA, the shopkeeper might find they have the following coins;
fourteen 1¢ coins
fifteen 5¢ coins
twenty eight 10¢ coins
fourteen 25¢ coins
twenty four ＄1 coins

... and also a large number of notes.

If it were in India the shopkeeper might find they have the following notes;
twelve ₹5 (rupees) notes
thirty two ₹10 notes
eighteen ₹20 notes
twenty seven ₹50 notes
four ₹100 notes

... and also some coins.

Which coin was the most common in the USA shop?
Which coin was the most common in the Indian shop?

The mathematical name for the most common item in a set of data is the 'mode'.

Can you think of a reason why the shopkeepers might be interested to know the modal number of coins?

You could search your room for collections of other things that can be sorted and then counted. You could then find the mode for them.
