Divide the class into groups.
Give them a square grid paper and instruct to draw a rectangle of
size of 5 × 7 on it. Here, the rectangle has 5 rows and 7 columns.

To represent on the rectangle, one student of each group will
5
colour its 4 rows in red as shown in the picture
3
To represent on the same rectangle, other students of group will
7
colour its 3 columns in blue.
Now, the pair will count the number of double-shaded squares and
the total number of squares in the rectangle.
Here, the number of double-shaded squares is 12 and the total
number of squares in rectangle is 35.
The fraction for double-shaded squares over the total number of
squares will be the required product. Here, fraction for double- 4
