What is it?

When we compare two or more objects based on their length, 'shorter than' means having less length. An object is shorter than another if it measures less from one end to the other.

Simple Example

Quick Example

Imagine you have two pencils. One pencil is 10 cm long, and the other is 7 cm long. The pencil that is 7 cm long is shorter than the pencil that is 10 cm long.

Worked Example

Step-by-Step

Let's compare the height of a cricket bat and a cricket stump.
---Step 1: Measure the length of the cricket bat. Let's say it is 96 cm long.
---Step 2: Measure the length of the cricket stump. Let's say it is 71 cm long.
---Step 3: Compare the two lengths: 96 cm and 71 cm.
---Step 4: We see that 71 is less than 96.
---Step 5: Therefore, the cricket stump is shorter than the cricket bat.
Answer: The cricket stump is shorter than the cricket bat.

Why It Matters

Understanding 'shorter than' is crucial in many fields like engineering, architecture, and even fashion design. Engineers use it to design parts that fit perfectly, architects to plan building dimensions, and designers to create clothes with the right lengths. It helps in making accurate measurements and comparisons.

Common Mistakes

MISTAKE: Confusing 'shorter than' with 'thinner than'. Students might think a thin object is always shorter. | CORRECTION: 'Shorter than' refers to length (how long something is), not width or thickness (how wide or thick something is). A short, thick object can be shorter than a long, thin object.

MISTAKE: Not starting the measurement from the same point when comparing. This leads to incorrect comparisons. | CORRECTION: Always align the starting points of the objects you are comparing to ensure an accurate measurement of their lengths.

MISTAKE: Only comparing two objects and not understanding that multiple objects can be ordered from shortest to longest. | CORRECTION: The concept applies to more than two objects. You can arrange several objects in increasing order of length, from the shortest to the longest.
