This is a day to day problem which can be taken mathematically:
There are 23 school buses each carrying 41 kids and teachers on a picnic to the Niagara Falls. How many total number of people are going in this trip?
Mathematically, the problem is
41 X 23 = ?
We know that 41 = 40 + 1.
? Place 40 and 1 in two columns as shown in the grid in the attachment.
? Similarly ...
