Locate numbers on a number line

A number line represents whole numbers in order, with positions increasing from left to right and equal intervals corresponding to equal changes in value. Learners locate and label whole numbers from 0 through 1,000, using marked ones, tens, or hundreds and benchmark points to determine position, compare numbers, and identify numbers between labeled points; negative numbers, fractions, decimals, and unscaled or generalized number lines are beyond this scope.

Detailed Explanation: Locate numbers on a number line

A number line shows numbers in order from left to right. Equal spaces mean equal changes in value.

To locate a number:

Find the labeled numbers around it.
Count how much each space is worth.
Count spaces from the smaller labeled number.
Label the correct point.

Example: Locate $340$ on the number line.

Suppose the number line goes from $300$ to $400$ and has $10$ equal spaces:

300 \quad \vert \quad \vert \quad \vert \quad \vert \quad \vert \quad \vert \quad \vert \quad \vert \quad \vert \quad 400

There are $100$ numbers from $300$ to $400$ , split into $10$ equal spaces:

100 \div 10 = 10

So, each space is worth $10$ .

Now count by tens from $300$ :

First mark: $310$
Second mark: $320$
Third mark: $330$
Fourth mark: $340$

Therefore, $340$ is at the fourth mark to the right of $300$ .
