Look at the picture and fill in the blanks. mEasUring LEngTH

1. Ranjan is __________ than Kavya. (shorter/taller) Using Body parts

2. The cupboard is _____________ than the window. (bigger/smaller) Long ago people used their body parts such as fingers, handspans, cubits, feet, etc.

3. The sofa on the left is __________ than the sofa on the right. (heavier/lighter) to measure lengths of objects.

Comparing LEngTHs

When we want to compare the lengths of two objects, we We use the words ‘tall’, handspan palm finger/digit cubit
can place them side by side. ‘short’, heavy, light, etc. to
measure something.
Let us compare the lengths of a toothpick and a toothbrush.

We see that the toothbrush is longer than the toothpick or the toothpick is shorter pace footspan armspan

than the toothbrush.

Now, compare the lengths of a crayon, a pencil and an eraser. Inaya and Ishan are placing their handspans
along the stick to measure its length.

Inaya: The length of the stick is 5 handspans.
We can clearly see that the pencil is the longest and the eraser is the shortest among Ishan: The length of the stick is 7 handspans.

the three items.
Think! Why do they get a different number of

handspans for the same stick?
Think Tank Experiential Learning Logical Thinking
For correct measurement, we always use an Inaya Ishan
1. Which one is taller?
object that is the same length.

Using small objects

Look at the following. Here, the length of a pencil is

2. Name an object that is measured using erasers.
(a) longer than your study table. ______________________

(b) shorter than your spoon. ______________________
3. Who among your family members is the tallest? ______________________ The pencil box is
4. Name an item which is shorter than an electric pole. ______________________ The pencil is 10 erasers long. 5 sharpeners long.
