# Worksheets

> Create practice sheets, homework, and assessments

Worksheets are one of the two project types in Checkfu (the other is [Slides](/projects/slides)). Use worksheets for practice problems, homework, assessments, or any printable activity.

## Create a Worksheet

1. Click **Projects** in the sidebar
2. Click **New Project**
3. Pick **Worksheet**
4. Describe what you want (example: "10 multiplication word problems for 3rd graders, increasing difficulty")
5. Pick your settings (see below)
6. Click **Generate**

## Worksheet Settings

When you create a worksheet, you can choose:

| Setting                 | Options                                     | What It Does                                                                 |
| ----------------------- | ------------------------------------------- | ---------------------------------------------------------------------------- |
| **Style**               | Playful, Standard, Academic, Visual, Custom | Changes the look of the worksheet. Pick "Custom" to describe your own style. |
| **Color Mode**          | Black & White, Color                        | Black & white is better for printing. Color is better for screens.           |
| **Orientation**         | Portrait, Landscape                         | Portrait is taller (like regular paper). Landscape is wider.                 |
| **Page Size**           | Letter, 4:3, 16:9                           | Letter is standard printer paper. The others are screen sizes.               |
| **Target Audience**     | Grade level or custom description           | Tells AI who the worksheet is for                                            |
| **Learning Objectives** | What students should learn                  | Helps AI create the right problems                                           |

**Style descriptions:**

* **Playful** - Rounded containers, icons, and visual cues. Good for younger learners.
* **Standard** - Clean headers, ruled lines, balanced spacing.
* **Academic** - Professional layout with formal structure. No decorations.
* **Visual** - One big diagram or visual per page with less text.
* **Custom** - Describe exactly what you want.

## The Editor

After AI creates your worksheet, you can change anything. The editor has three parts: a page list on the left, the canvas in the center, and a settings panel on the right.

| What You Want to Do   | How to Do It                                 |
| --------------------- | -------------------------------------------- |
| Move around the page  | Hold **Space** and drag                      |
| Zoom in or out        | Hold **Ctrl** (or **Cmd** on Mac) and scroll |
| Select something      | Click on it                                  |
| Select several things | Hold **Shift** and click each one            |
| Move something        | Drag it                                      |
| Resize something      | Drag the corner handles                      |
| Add a new page        | Click **+** in the page list                 |

You can edit text (bold, italic, lists, math with LaTeX), add images (AI-generated or uploaded), and adjust settings for any selected element in the right panel.

### Math Equations

Type LaTeX between `$` symbols. Example: `$x^2 + y^2$`

## Printing and Exporting

### Print

1. Click the **menu** (three dots) in the left panel
2. Click **Print**
3. Use your browser's print window

**For best results:**

* Set paper size to "Letter"
* Set margins to "None"
* Turn on "Background graphics" if you want colors to show

### Export as PDF

1. Click the **menu** in the left panel
2. Click **Export PDF**
3. The file downloads to your computer

<Note>
  On the Free and Starter plans, exported PDFs include a small "made with checkfu.com" footer. The Pro plan removes this.
</Note>

## Answer Keys

An answer key shows the correct answers for your worksheet. This makes grading faster and lets AI help grade student work.

### Create an Answer Key

1. Open your worksheet in the editor
2. Click **Generate Answer Key** in the toolbar
3. AI looks at your worksheet and creates answer pages

The answer key pages get added to your project with an "Answer Key" label.

### How Answer Keys Work

* Answer key pages have a label so you can tell them apart
* They are hidden from students who view the project online
* When you print, you can choose to include or leave them out

### What's in the Answer Key

Depending on your worksheet, the answer key may show:

* Filled-in answers for blanks
* Step-by-step solutions for math problems
* Correct answers for multiple choice
* Example responses for open-ended questions

### Using Answer Keys for Grading

When students turn in work through a course, the answer key lets:

* **AI grade automatically** by comparing student answers to the key
* **Give partial credit** for work that's partly right
* **Write feedback** based on what the student got wrong

<Tip>
  Always check AI-generated answer keys for accuracy, especially for word problems and multi-step questions.
</Tip>

## Variations

Variations are different versions of the same worksheet. The questions change, but the format and difficulty stay the same.

### Why Use Variations?

* **Test security** - Different versions so students can't copy
* **Different levels** - Easier version for some students, harder for others
* **Extra practice** - More problems on the same topic
* **Retakes** - A fair second chance with new questions

### Create a Variation

1. Open your worksheet in the editor
2. Click **Generate Variation**
3. Pick what kind:

| Option         | What It Does                                        |
| -------------- | --------------------------------------------------- |
| **Same Level** | Different questions, same difficulty                |
| **Easier**     | Simpler problems for students who need more support |
| **Harder**     | Tougher problems for students who need a challenge  |
| **New Look**   | Same content, different layout                      |

4. Add any special instructions (optional)
5. Click **Generate**

Each variation becomes its own project that you can edit separately.

<Tip>
  Make sure your original worksheet is finished and correct before making variations. AI uses the original as a guide.
</Tip>

## Templates

When you create a new project, you can pick a style preset that acts as a template. It controls layout, question formats, and spacing. Pick one close to what you want, then change anything after AI generates the content.

## Keyboard Shortcuts

| What You Want to Do | Shortcut             |
| ------------------- | -------------------- |
| Undo                | Ctrl/Cmd + Z         |
| Redo                | Ctrl/Cmd + Shift + Z |
