In Levels 4 and 5, you learned how to type documents in a Word Processor and calculate data in a Spreadsheet. But what if you have a great idea and you need to convince your school assembly, your teachers, or your community elders to take action? You need a Digital Presentation!
1. Plain Talk: The Speaker & The Signboard
Imagine the senior school prefect speaking at morning assembly. If they hold up a giant cardboard sign with an entire textbook page written in tiny handwriting, no student can read it. But if their sign has a bold 3-word title and one clear drawing, everyone understands in a flash!
Presentation software (like Microsoft PowerPoint, Google Slides, or LibreOffice Impress) lets you create digital signboards called Slides. The slides project behind you on a screen or TV to support your voice.
Figure 23.0: Anatomy of presentation software. Slides run down the left, and the active slide is built in the center.
2. Essential Presentation Vocabulary
Slide: A single digital page or screen in your presentation.
Slide Deck: The complete collection of all slides saved together in one file.
Placeholder: The dotted rectangular boxes on a slide that say "Click to add title" or "Click to add text".
Speaker Notes: Private written reminders at the bottom of the screen that only you can see on your laptop.
The 6x6 Design Law & Contrast
Session 23 • Page 2
1. The Cardinal Presentation Law
👑 THE SPEAKER'S GOLDEN RULE:
SLIDES ARE MEANT TO SUPPORT YOU, NOT REPLACE YOU!
If you type every single word on your slide and stand with your back to the audience reading it out loud like a robot, your audience will fall asleep. Your slides should show keywords and pictures; your voice tells the story!
2. The Famous "6-by-6" Rule
Follow this simple rule to keep your slides clean, readable, and punchy:
1. Maximum 6 Bullets
Never put more than 6 bullet points on a single slide. If you have 8 points, split them into two slides!
2. Maximum 6 Words
Keep each bullet point to a maximum of 6 words. Use strong keywords instead of long, full sentences.
Figure 23.1: The 6x6 rule in action. Short phrases let the audience listen to the speaker.
3. High Contrast: Colors That Work
✅ EXCELLENT Color Combinations
❌ TERRIBLE Combinations (Unreadable!)
Deep Navy or Black text on a Pure White / Cream slide.
Yellow text on a White background (invisible!).
Crisp White text on a Deep Purple or Dark Blue slide.
Red text on a Green background (blurs human eyes).
Slide Layouts & Aspect Ratio
Session 23 • Page 3
1. Standard Slide Layouts
When you click "New Slide" on the ribbon, the software asks you which layout you need:
Title Slide: Used for Slide 1 only. Contains a giant Title box and a Subtitle box.
Title and Content: The workhorse layout. Has a title at the top and a large bulleted box below.
Two Content: Divides the slide into two columns (great for text on the left and a picture on the right!).
Using Google Slides or LibreOffice Impress? The buttons look a little different but do the same job.
2. The Aspect Ratio Law: Never Squish a Picture!
When you click a picture, eight small sizing dots (handles) appear around its border. How you drag them matters enormously:
Figure 23.2: Resizing images. Always drag from the CORNER handles to preserve the natural proportions.
3. Panic Button / Troubleshooting
🚨 MY PICTURE LOOKS SQUISHED LIKE A SMASHED PLANTAIN!
Don't panic! You accidentally dragged a middle-side handle instead of a corner handle.
How to fix it: Immediately press Ctrl + Z to undo the resize. Then, find one of the four circular corner handles, click, and drag diagonally!
Planning on Paper: The 3-Slide Storyboard
Session 23 • Page 4
1. Why Professionals Plan on Paper First
The greatest mistake beginners make is opening presentation software immediately and getting distracted by fancy animations and colors. Expert presenters always plan on a sheet of paper first using a Storyboard (a sequence of quick hand-drawn sketch boxes).
2. The Classic 3-Slide Action Formula
For your Tech Club projects, you will use this powerful 3-step narrative arc:
Figure 23.3: The 3-Slide Storyboard. Hook the audience, state the challenge, and present the practical fix.
3. Presentation Shortcut Pro-Tip
F5 Key : Starts your full-screen Slide Show from Slide 1!
Esc Key : Exits the slide show and returns to the editor.

SLIDE 2: The Problem (Bullets)
SLIDE 3: The Solution (Bullets)
2. Written Review Questions
Question 1: State the two parts of the 6-by-6 Rule for slide design:
Question 2: Why should you always resize pictures using the corner handles instead of the side handles?
Question 3: What key on your keyboard launches the full-screen Slide Show? Answer: Key _________
