Key Point: Image pixel size: Total pixels = width (pixels) × height (pixels). Example: 800 × 600 = 480,000 pixels.
What is Paint/Drawing software?
Paint (or simple drawing programs) is a computer application that lets you create pictures and color drawings on the screen using tools such as pencil, brush, shapes, fill (paint bucket), eraser and text. The empty area where you draw is called the canvas.

Making birthday cards, school posters, labeling images for a project, creating simple diagrams, practicing digital art and coloring scanned drawings.
Key Point: Canvas pixel count = width (pixels) × height (pixels). Explains how many tiny dots make the picture.
What is the Paint Workspace and Interface?
The Paint workspace (or interface) is the on-screen area where you create, edit and save drawings using the Paint program. It is made of different parts such as the canvas where you draw, toolbars that hold drawing tools, the color palette, menus and status information.
Main parts of the Paint interface (with simple descriptions):
How children use the Paint workspace (basic steps):
Simple tips to work well:
Key Point: Perimeter of a rectangle = 2 × (length + width). Example: length = 10 units, width = 4 units → Perimeter = 2 × (10 + 4) = 28 units.
Drawing Tools are the set of instruments in a painting or drawing program (and their real-life equivalents) that help you make lines, shapes, colours and designs. In a computer Paint program these tools are usually shown on a toolbar and let you draw freehand, create perfect shapes, fill areas with colour, erase mistakes and add text.

Tips for good drawings:
Real-life equivalents: pencil, brush, eraser, ruler, compass, stencil and colour paints — these help you practise the same skills on paper as the computer tools do on the screen.
Key Point: Rectangle area = length × width (A = l × w); perimeter = 2 × (length + width) (P = 2(l + w)).
What are Shape Tools?
Shape Tools are buttons in a paint or drawing program (like MS Paint) that let you draw ready-made geometric shapes quickly: rectangles, circles (ovals), lines, triangles, rounded rectangles, stars, arrows and more. Instead of drawing a shape freehand, you click a shape icon, choose outline and fill colors, set thickness, then click-and-drag on the canvas to place the shape.
How to use them (simple steps):
Important options and effects
Why it matters for young learners
Shape Tools help children make neat drawings (houses, trees, faces) while learning geometric names and measurements. They also teach using tool options (colors, thickness, fill) and basic composition (putting shapes together to make pictures).
Key Point: Primary (paint) mixing (simple rules used in art class): Red + Blue = Purple; Red + Yellow = Orange; Blue + Yellow = Green
What is a Color Palette?
A color palette is a set of colours you can choose from when you draw or paint on a computer. In simple drawing programs (like MS Paint), the palette shows small colour boxes. You click a colour to make it the active colour for drawing, filling, or writing.
What is the Fill tool?
The Fill tool (often shown as a paint bucket) fills an area with the chosen colour. When you click inside a closed shape, the tool replaces the shape's inside with the selected colour. The shape must be fully closed (no gaps) or the fill may spill outside.
How they work together
Tips and important points
Colour basics for children
There are primary colours for paint (subtractive): red, yellow and blue. Mixing them makes secondary colours: red + blue = purple, red + yellow = orange, blue + yellow = green. In computer screens (additive colour), the primary lights are Red, Green and Blue (RGB). Combining R, G and B in different amounts makes all the colours you see on the screen.
Simple technical idea (age-appropriate)
When you use Fill, the program checks the colour of the pixel you clicked and changes that pixel and all nearby pixels of the same (or similar) colour to the new colour. This is often called a flood-fill or boundary-fill action.
Key Point: Percentage of area erased = (Erased area / Total area) × 100
What is the Eraser?
The Eraser is a tool in Paint and drawing programs that removes parts of your picture. It works like a real rubber eraser used on paper — when you drag it over a drawing, the pixels under the eraser are removed or replaced by the background color (or become transparent, depending on the program).
How to use the Eraser (steps):
Cleanup tools and actions:
Tips for good cleanup:
Difference between erasing and drawing with background color:
Some programs erase to make pixels transparent; others replace erased pixels with the current background color. If you want a true "erase" (transparent), make sure the program supports layers or transparency.
When to use Cleanup: After drawing, cleanup helps remove stray marks, smooth edges, correct small mistakes, and prepare the picture for coloring or printing.
Key Point: Select -> Drag -> Release = Move
What is Selection? Selection means choosing a part of your picture or drawing so you can change it without affecting the rest. In Paint there are usually two kinds of selection tools: rectangular selection (a box) and free-form selection (any shape).
How to select: Choose the Select tool, click and drag around the part you want. You will see a dashed border (marching ants) or small squares (handles) around the chosen area.
Moving a selection means taking the selected part and placing it somewhere else on the same picture. After selecting, move the cursor inside the selected area, click and drag to the new position. Release the mouse button to drop it. You can also use the arrow keys for small moves.
Copying a selection makes a duplicate of the selected area while the original stays where it was. To copy: select the area, press Ctrl+C (or use the Copy command), then Ctrl+V (or Paste) to place a copy. You can move the pasted copy to any place.
Cutting (move by remove) removes the selected part from its original place and lets you paste it elsewhere. Use Ctrl+X (Cut) then Ctrl+V (Paste).
Extra tips:
Why learn this? Selection, moving and copying help you arrange pictures, repeat patterns, fix mistakes, and make collages quickly—just like moving stickers on paper.
Key Point: Resize (scaling by factor s): new_width = s × old_width ; new_height = s × old_height. If s is percent p%, then s = p / 100 (for example 150% → s = 1.5).
Resize, Rotate and Skew are simple ways to change how a picture or shape looks in a drawing or paint program.
Resize (Scale): To resize means to make an image or shape larger or smaller. When you resize, you change the width and height. Most programs let you type a percent (for example 200% makes it twice as big, 50% makes it half as big) or drag a corner handle to stretch or shrink the object. If the program keeps the aspect ratio locked, the shape keeps its original proportions and does not get stretched oddly.
Rotate: To rotate means to turn an object around a fixed point (usually its center). You choose an angle (for example 90°, 180° or 45°) and the object spins by that angle. Rotating by 90° turns a picture from portrait to landscape and vice versa.
Skew (Shear): Skewing slants an image or shape so its top and bottom (or left and right) move sideways in different directions. It looks like the object is leaning. Skew is often used to create an italic or slanted effect or to make simple perspective changes.
How these look in a drawing program:
Tips for students: Always watch the proportions when resizing (lock aspect ratio if needed), set a clear rotation angle for exact turns (90°, 180°), and use small skew values to avoid too much slanting.
Key Point: Line height ≈ 1.2 × font size (useful to estimate space needed for each line of text).
The Text Tool is used to add typed words or letters onto your drawing. In Paint (and similar drawing programs) it usually looks like the letter A or a T. You click the Text Tool, then click (or click and drag) on the drawing area to make a text box. Type your words, and use the tool settings to choose the font (typeface), font size, style (bold, italic, underline), color and alignment (left, center, right).
Important points for Class 4 students:
Why it is useful: you can add names, labels, titles, captions and instructions directly on drawings, posters, greeting cards and school projects. It helps make pictures clear and informative.
Key Point: Color as RGB triple: Color = (R, G, B) where R, G, B are integers 0–255. Example: pure red = (255, 0, 0).
Color Picker (Eyedropper)
The Color Picker (also called Eyedropper) is a tool in drawing programs that copies a color from anywhere on the canvas or an image so you can use the exact same color elsewhere. When you click on a pixel with the eyedropper, the program reads that pixel's color and sets it as the current drawing (foreground) color.
How to use (simple steps):
Why it is useful: it helps you match colors exactly (for example, matching a shirt color in a photo), keeps your design consistent, and saves time selecting colors manually.
Outline (for shapes and objects)
The Outline is the border drawn around a shape. Most drawing programs let you set:
How to use outline with shapes:
How Color Picker and Outline work together: use the Color Picker to select a color from the image, then set that color as the Outline color so borders match elements already in your picture. This gives a neat, coordinated look.
Key Point: If states are S0 (start), S1 (after first action A1), S2 (after A2), ... then: Undo from Sn -> Sn-1, Redo from Sn-1 -> Sn.
Undo means taking back the most recent change you made in a program (for example: removing the last brush stroke in Paint). Redo means putting that change back again if you changed your mind after an undo. Editing history is the record of all the changes (actions) you made while working on a picture, document or drawing.
How it works (simple):
Simple rules children can remember:
Common buttons and shortcuts: Undo button (curved left arrow), Redo button (curved right arrow), Ctrl+Z for Undo, Ctrl+Y or Ctrl+Shift+Z for Redo (depends on the program).
Limitations: Some apps remember only a fixed number of steps (for example 20). When you save and close a file, some programs clear the undo history.
Key Point: Displayed size = Original size × (Zoom percentage / 100). Example: at 200% a 50 px line appears as 50 × (200/100) = 100 px on screen.
What is Zoom? Zoom is a view feature in Paint and other drawing programs that makes the picture look bigger (zoom in) or smaller (zoom out) on your screen without changing the actual picture file. Zoom helps you see small details or the whole picture.

Key Point: Approximate uncompressed image size (bytes) = width (pixels) × height (pixels) × color depth (bits) ÷ 8
What is Saving?
Saving means keeping your drawing or picture on the computer so you can use it later. When you save, the computer writes your work into a file and stores it on a disk, folder, pen drive or cloud storage.
How to save (simple steps)
1. Click the File menu and choose Save or Save As.
2. Pick a place (folder) where you want to keep the file (for example Desktop or Documents).
3. Type a name for the file. Use letters and numbers; avoid special symbols like / \ : * ? " < > | .
4. Choose a file format (see below).
5. Click Save.
Tip: Use Ctrl+S to quickly save while working.
What is Opening?
Opening means telling the computer to load a saved file so you can view or edit it. To open: click File > Open, find the file in the folder, select it and click Open. Shortcut: Ctrl+O.
Common file formats for pictures
- BMP (.bmp) – uncompressed, very large files, good for simple programs but takes much space.
- JPEG/JPG (.jpg or .jpeg) – compressed, makes photos smaller with some loss of detail; good for photos and sharing by email.
- PNG (.png) – compressed without losing quality, supports transparency (see-through parts); good for drawings and images that need clear edges.
- GIF (.gif) – small images with few colors; can be used for simple animation.
- TIFF (.tif) – used for high-quality printing, not usual for small school work.
How to choose a format
- For school drawings or line art choose PNG (keeps lines sharp).
- For photographs choose JPG (smaller file size).
- For animations choose GIF (if simple colors).
- If you want the largest, exact copy (no compression), choose BMP or TIFF (but these use a lot of storage).
Why saving often is important
Saving often stops loss of work when the computer crashes or power goes off. Use different names like MyDrawing1.png, MyDrawing2.png to keep earlier versions.
Key Point: Total printing cost = number of copies × cost per copy (currency units)
What is Printing? Printing means making a paper copy of a picture or drawing that you made in Paint. You use a printer connected to your computer. Before printing, you can check how the picture will look on paper using Print Preview and change settings like paper size, orientation (portrait or landscape), number of copies, and color options.
How to Print (simple steps):
What is Sharing? Sharing means sending your picture to someone else so they can see it. You can share by saving the file and using email, messaging apps, a USB drive, or cloud storage (like Google Drive). You can also save as different file types (PNG, JPEG, BMP, PDF) depending on how you want to share.
How to Share (simple steps):
Tips for good printing and sharing:
Safety and etiquette: Always check with a parent or teacher before sending or sharing pictures online. Do not share private information in pictures.
Key Point: Area = Width × Height (e.g., area in pixels = width in pixels × height in pixels)
What is Canvas Size?
The canvas is the blank area where you draw in a paint program. Canvas size means how wide and how tall that blank area is. It is measured in units such as pixels (for computer screens) or centimetres/inches (for printing).
Why canvas size matters
- A larger canvas gives you more space to draw details.
- A smaller canvas makes the drawing take less memory and can be easier to share.
- If you change the canvas size without keeping the correct shape, your picture may stretch or squash.
How to change canvas size (simple steps)
1. Find the Resize or Canvas Size option in the paint program.
2. Choose units (pixels or percent).
3. Enter new width and height.
4. Keep aspect ratio locked if you want to avoid distortion.
5. Confirm to apply the change.
What is Background?
The background is the colour or image that fills the canvas behind your drawing. You can choose a single colour (for example blue for the sky), a pattern, or leave it white or transparent depending on the program.
How to set background
- Use the Fill tool (bucket) to fill the whole canvas with one colour.
- Set background when creating a new file (choose background colour).
- Place a picture as the background layer and draw on top if the program supports layers.
Practical tips for children
- For screen drawings (e.g., sharing online): use pixels and choose a moderate size (for example 800×600 px).
- For printing (posters or cards): choose size in cm or inches and set higher resolution if asked.
- Choose a background colour that makes your main drawing easy to see (light background for dark drawings and vice versa).
- Always save a copy before resizing so you don’t lose the original.
Key Point: Position of a stamp: (x, y) — the coordinates where you click on the canvas place the stamp center or corner depending on the program.
What are stamps, stickers and special effects?
In a paint or drawing program, stamps and stickers are ready-made pictures that you can place on your drawing with a click. Special effects are tools that change how a picture looks—examples are shadows, transparency (see-through), blur, glow and color filters.
Stamps: A stamp is a small image (for example a star, flower or animal) that you can stamp many times on your picture. Stamps save time and help make repeated shapes look the same.
Stickers: A sticker is like a cut-out picture that you can stick anywhere on the canvas. Stickers can be larger and can be moved, rotated or resized after you place them—like putting a paper sticker on a notebook.
Special effects: These change the appearance of stamps, stickers or any drawing. Examples are:
How to use them (simple steps):
Tips for good results
Digital vs real-life examples: Digital stamps are like rubber stamps on paper. Digital stickers are like adhesive stickers you buy for scrapbooks. Special effects in a program are like adding a shadow with a pencil or rubbing glitter glue for shine.
Key Point: Scale factor (to resize proportionally) = new size ÷ original size. Example: If original width = 200 px and you want 50% size, scale factor = 0.5 and new width = 200 × 0.5 = 100 px.
This topic helps young learners use Paint and simple drawing programs better by following helpful tips, doing fun activities and following good practices. The ideas below are written in simple steps so children can draw, colour and save their work easily and safely.
Following these tips, doing the activities and using good practices will make using Paint more fun and help children produce neat, memorable artwork.
Key Point: Think + Ask = Safe Share (Think about what’s in the picture, Ask an adult if unsure)
What is Digital Safety? Digital safety means using computers, tablets and the internet in a way that keeps you, your work and your personal information safe. When you draw in Paint or other drawing apps, you should be careful about what you save, share and click on.
What is Digital Etiquette? Digital etiquette means being polite and respectful when you use devices or share pictures online. It is about treating others the way you want to be treated, even when you are using Paint, sending drawings or commenting on someone else’s art.
Important safety rules (simple and clear):
Good digital manners (etiquette):
How to decide before sharing a drawing: Stop and think: Does the drawing include my address, phone number, school name, or full name? If yes, don’t share publicly. If you are unsure, ask a parent or teacher.
What to do if something bad happens: Tell a trusted adult, save any messages or pictures that show the problem, and block or report the person if they are being mean or sending harmful content.
