## What this block does
A Categorize Activity asks students to drag items into categories. Use it to distinguish related concepts, classify examples, or check whether students can apply a rule.

## How to use it
1. In lesson Edit mode, type **/** and choose **Categorize Activity**.
2. Name the categories and add the items to classify.
3. Assign each item to its correct category in the instructor solution.
4. Set the block’s **Points** and preview the learner view. Items are shuffled for students.
5. Test correct and incorrect placements before publishing.

## Example
Create categories **Physical change** and **Chemical change**. Add **Melting ice**, **Cutting paper**, and **Rusting iron**, then assign each to its correct category.

## Grading and practice
The activity checks each item against its assigned category. Keep labels unambiguous and review the saved solution if a placement is rejected. Add [Instant Feedback](https://www.curacourse.com/help/instant-feedback) for practice checks, or use normal lesson submission for assessment.
