Learning by Doing

objective: To represent the fractional quantities using fractional units by paper
folding.
Materials required: A strip of paper.
Procedure:

• Start with a strip of paper.

1 Strip paper
• Fold the paper strip in half so that the two ends meet, then unfold it to get a crease in
the middle.

• As the whole strip is 1 unit long. So the crease divides the strip into two equal parts, so
 1
each part is half   of the whole strip as shown below.
2


1 1
2 2
• Now, fold the strip in halves again and unfold it to get two more creases, that divide the
strip into four equal parts as shown below.

1 1 1 1
4 4 4 4

2 times
4 4 2
• Again fold the strip in halves that divides the strip into eight equal part. Again fold it to
get 16 equal parts.

2 times = = Fractional quantities can be measured using fractional units.
16 16 8
Each time we fold the strip, the number of parts doubles, and size of each part gets smaller.
observation:

Complete the blank spaces:

1 1 1 1
4 times = 6 times = 9 times = 16 times =
16 16 16 16

Thus, this activity is useful in understanding the fractional quantities.
