# Number Line Question Block

> Learn how to use Number Line Question blocks to create interactive activities where learners place values on a number line.

The **Number Line Question** block creates interactive activities where learners place a marker on a number line to identify a specific value. It supports whole numbers, fractions, and decimals.

> [!NOTE]
>
> Number Line Questions support both slider-based (drag the marker) and typed answer modes.

## When to use Number Line Questions

Number Line Questions work well for:

* Identifying positions of whole numbers, fractions, or decimals
* Rounding to the nearest ten, hundred, or other value
* Estimating positions between labeled tick marks
* Reading values from partially labeled number lines
* Practicing fraction and decimal placement

## Settings

### Number line settings

**Minimum value** `input` (default: 0)

The starting value of the number line.

**Maximum value** `input` (default: 10)

The ending value of the number line.

**Tick interval** `input` (default: 1)

The spacing between tick marks on the number line.

**Major ticks** `input` (default: 0, 5, 10)

Specific values that display with longer, more prominent tick marks.

**Show minor ticks** `switch` (default: true)

When enabled, displays smaller tick marks between major ticks.

**Labels** `select` (default: All ticks)

Which tick marks show numeric labels:

* **All ticks**: Labels on every tick mark
* **Major only**: Labels only on major tick marks
* **No labels**: No numeric labels shown

**Label format** `select` (default: Decimals)

How values are displayed on the number line:

* **Decimals**: Shows values as decimal numbers
* **Fractions**: Shows values as fractions

### Display settings

**Orientation** `select` (default: Horizontal)

The orientation of the number line:

* **Horizontal**: Left to right layout
* **Vertical**: Bottom to top layout

**Show endpoint arrows** `switch` (default: true)

When enabled, displays arrows at both ends of the number line.

**Width** `slider` (default: 600)

The width of the number line in pixels (80 to 1200).

**Height** `slider` (default: 120)

The height of the number line in pixels (80 to 500).

## Answer and marking

Set the correct answer by specifying the target value on the number line. You can choose between:

* **Slider**: Learners drag a marker to the correct position
* **Typed**: Learners type their answer

Marking can be **exact** (the answer must match precisely) or **tolerance-based** (answers within a range are accepted). Tolerance can be set to half a step or a custom value.

## Response settings

**Response requirement** `select` (default: Correct)

Determines when the question is considered complete:

* **Correct**: The learner must answer correctly to proceed.
* **Answered**: Any response is accepted; correctness isn't required.
* **Optional**: The learner can skip the question entirely.

**Max responses** `slider` (default: 0)

The number of attempts the learner can make before the question is locked (0–3). Set to **0** for unlimited attempts.

**XP points** `slider` (default: 5)

The experience points awarded for answering the question correctly (0–10).

## Tips for teachers and parents

**Best practices:**

* Use **Major only** labels to create more challenging activities where learners must count between labeled values
* Set the label format to **Fractions** when teaching fraction placement
* Start with whole numbers and familiar ranges before moving to decimals and fractions
* Use tolerance-based marking for estimation activities
* Remove minor ticks to increase difficulty
* Pair with a Number Line display block to model the concept first
