What is it?
Numbers that are 'more than twenty' are any numbers larger in value than 20. This means they come after 20 when you count upwards, like 21, 22, 23, and so on.
Simple Example
Quick Example
Imagine your favourite cricket team scored 20 runs in the first 5 overs. If they score 25 runs in the next 5 overs, then 25 is 'more than twenty'. It's a bigger score!
Worked Example
Step-by-Step
QUESTION: Is 23 more than 20?
STEP 1: Identify the two numbers we are comparing: 23 and 20.
---STEP 2: Think about counting. If you start counting from 1, you say 1, 2, ..., 19, 20, 21, 22, 23, ...
---STEP 3: Notice that 23 comes AFTER 20 when counting.
---STEP 4: Numbers that come after another number when counting are larger, or 'more than' that number.
---ANSWER: Yes, 23 is more than 20.
Why It Matters
Understanding 'more than' helps you compare quantities in daily life and in many subjects. It's crucial in Maths for addition, subtraction, and understanding number lines. Engineers use it to compare measurements, and business analysts use it to compare sales figures or profits.
Common Mistakes
MISTAKE: Thinking 20 is more than 20. | CORRECTION: 'More than' means strictly greater. 20 is equal to 20, not more than 20.
MISTAKE: Confusing 'more than' with 'less than'. For example, saying 19 is more than 20. | CORRECTION: 'More than' means a larger number. 19 comes before 20 when counting, so it's less than 20.
MISTAKE: Only considering whole numbers. For example, thinking 20.5 is not more than 20 because it's not a whole number like 21. | CORRECTION: Any number, including decimals and fractions, that is larger than 20 is 'more than twenty'. 20.5 is indeed more than 20.
