Comparison of Measurements – EP – 2
3 Minutes
Comparison of measurements for kids explains light vs heavy and short vs long using balls and pencils. A short maths lesson in English.
- Lifting two different balls to compare light and heavy weights
- Sharpening a pencil down until it becomes short
- Comparing the lengths of two pencils to see short and long
What this lesson teaches
Comparing measurements is the process of looking at two or more objects to see how they differ in physical qualities like weight and length. By testing and observing these differences, objects can be classified using pairs of opposite terms such as light and heavy, or short and long.
Understanding light and heavy
When an object is easy to lift, it is light because it has less weight. In contrast, an object that requires effort and causes a person to struggle to lift is heavy. Comparing the weight of two balls by picking each one up demonstrates whether an object is light or heavy.
Understanding short and long
Length refers to how far an object extends from one end to the other. When comparing two pencils, one pencil can be significantly smaller in size, making it short. Another pencil can have greater size, which makes it long.
How pencil sharpening shows length
When a pencil lead breaks and the pencil is repeatedly sharpened, it gets worn down and decreases in size. A pencil that has been turned inside a sharpener over and over becomes noticeably short. Placing this worn pencil next to an unsharpened pencil clearly shows the difference between what is short and what is long.
Observing differences in objects
- Comparing two balls reveals that objects can have different weights, with one being light and one being heavy.
- A light object is lifted with ease, while a heavy object requires much more effort to raise.
- Comparing two pencils shows that objects of the same kind can differ in size, with one being long and the other being short.
- Continuous sharpening reduces an object down until it becomes short.
