# 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.

<Info>
  Number Line Questions support both slider-based (drag the marker) and typed answer modes.
</Info>

## 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

<ParamField path="Minimum value" default="0" type="input">
  The starting value of the number line.
</ParamField>

<ParamField path="Maximum value" default="10" type="input">
  The ending value of the number line.
</ParamField>

<ParamField path="Tick interval" default="1" type="input">
  The spacing between tick marks on the number line.
</ParamField>

<ParamField path="Major ticks" default="0, 5, 10" type="input">
  Specific values that display with longer, more prominent tick marks.
</ParamField>

<ParamField path="Show minor ticks" default="true" type="switch">
  When enabled, displays smaller tick marks between major ticks.
</ParamField>

<ParamField path="Labels" default="All ticks" type="select">
  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
</ParamField>

<ParamField path="Label format" default="Decimals" type="select">
  How values are displayed on the number line:

  * **Decimals**: Shows values as decimal numbers
  * **Fractions**: Shows values as fractions
</ParamField>

### Display settings

<ParamField path="Orientation" default="Horizontal" type="select">
  The orientation of the number line:

  * **Horizontal**: Left to right layout
  * **Vertical**: Bottom to top layout
</ParamField>

<ParamField path="Show endpoint arrows" default="true" type="switch">
  When enabled, displays arrows at both ends of the number line.
</ParamField>

<ParamField path="Width" default="600" type="slider">
  The width of the number line in pixels (80 to 1200).
</ParamField>

<ParamField path="Height" default="120" type="slider">
  The height of the number line in pixels (80 to 500).
</ParamField>

## 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

<ParamField path="Response requirement" default="Correct" type="select">
  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.
</ParamField>

<ParamField path="Max responses" default="0" type="slider">
  The number of attempts the learner can make before the question is locked (0–3). Set to **0** for unlimited attempts.
</ParamField>

<ParamField path="XP points" default="5" type="slider">
  The experience points awarded for answering the question correctly (0–10).
</ParamField>

## 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
