A slide changes with a click, not a dance to the laptop.
Every run to the desk is a back. A back is a moment when the class packs a backpack and loses the sentence. The space bar, an arrow, a school clicker. That is enough. A mouse on a desk by the wall turns you. A laptop on the floor bends you. Put the keyboard where you stand. On a school PC ask where the keyboard may stand, and if they have a clicker. Do not install a weird driver app from an advert. Do not make an account for that. A parent or the school holds the account. The space bar does not want a password. Today five slides facing the door. Thumb on the space. Arrow left once back, so you know you can also return. The body stays with people. The laptop only turns slides. You stand facing. A parent holds the account. No clicker app from an advert. No child’s account because of a remote. The space bar does not want a password. Today five slides facing is enough, so the thumb knows where the space is even in the dark.
Sofie ran to the desk at every slide. The class saw a back. Voice vanished at HDMI. Filip put the keyboard by his feet, thumb on the space bar, five slides facing. After practice Sofie pushed the mouse away. The thumb learned the space. She stopped dancing. A parent from the door saw Sofie’s back at every slide. After pushing the mouse away they saw a face. Filip pulled the keyboard to her feet. The thumb stayed on the space. Arrow left once returned a slide when they jumped ahead. They did not mix Esc with the next slide.
Hands off the mouse before you click Present (F5). Thumb on the space bar. The mouse is a trap for your back.
The thumb turns. The body stays.
Click Present (F5). Hands off the mouse. Space bar five times forward. Arrow left once back. Facing the door the whole time. In PowerPoint the same. Pull the keyboard in. Do not leave a laptop behind you on the desk. When school has a clicker, ask the teacher how it pairs — with no install of an app from an advert, with no child’s account. Practice of the whole with the space bar even with a stopwatch. When you reach for the mouse, return the thumb to the space. Arrow up and down sometimes change slides too. Check that as a dummy run, so at the board you do not run into a menu. Esc takes you back to edit. That is not the next slide. That is the end of speech. Trước khi bắt đầu, you know which key is the space bar even in the dark. A parent’s account. An email does not belong on a slide. On a school PC ask where the keyboard may stand. When they have a clicker, let the teacher pair it, not an advert. Practice of the whole with the space bar and a stopwatch shows if you reach for the mouse from habit.
Wrong: Sofie, a run at every slide, a back, the sentence between runs vanished.
Right: Filip, the space bar, facing, five slides. The body holds. The laptop only clicks.
Even without a clicker box you are a remote. The space bar is that box. Equally wrong is a laptop on the floor. You bend, the back goes, voice vanishes. Right is a table to the side, the keyboard with you, face to the door. Even without a clicker box you are a remote. The space bar is that box. Thumb on the space even in the dark. Esc is not the next slide. The mouse stays pushed away the whole speech.
Do not install a clicker driver from an advert. A school clicker, or the space bar. No child’s account. No shady app.
Four things you will build in this course
The course has four small projects. You do not have to do them all at once. Today you add only this:
🎯 A hobby in 5 slides
Five slides about something you like doing. One sentence about what it is. No paragraphs from your notebook.
Hobby: five slides a thumb can carry. A run to the mouse carries fewer, because you lose time.
📚 A report
Eight slides for school: a start, three proofs, an end. The title on every slide is a sentence, not “Slide 3”.
Report: eight slides with no runs. Otherwise the stopwatch eats the handoff between you and the desk.
📊 Survey results
A chart from a table (not a screenshot from chat) and under it where the numbers come from.
Survey: at a chart a second of eyes, the space bar only when you finish saying the meaning.
⚖️ A defence
You say one sentence, show proof, answer “and what if…”. If you do not know, you say I don’t know.
Defence: a run to the mouse at a question from a desk looks like a run.
Five slides with no mouse
Mouse pushed away. Thumb on the space. Facing the door.
-
Open Slides with at least five slides. Push the mouse away. Pull the keyboard to the place where you stand. Present (F5).
-
Space bar five times forward. Arrow left once back. Face to the door. You do not touch the mouse.
-
Esc. When you reached for the mouse, repeat. In PowerPoint the same keys: Present (F5), space bar, arrows, Esc.
-
Ask a parent or a teacher if school has a clicker. If not, the space bar is enough. No app from an advert.
-
Practice of the whole with the space bar. A stopwatch may run. A parent’s account. No email on a slide. File saved on Drive.
The mouse is a trap
When you reach for the mouse, the back already goes. The thumb can do it.
-
Push the mouse off the desk as a dummy run. Five slides only with the space bar.
-
Find the space bar on the keyboard even in the dark. Leave the finger there.
-
Find out what Esc does on a school PC. So at the board you do not run out of speech by mistake.
Now you 💪
- I can turn five slides with no mouse.
- I stand facing the door the whole time.
- If I do not know about a clicker, I can do the space bar.
Done when: You turn five slides with the space bar facing the class. You did not run to the mouse.
What to take from this lesson
- The space bar or a school clicker. Not a run to the mouse.
- The keyboard where you stand.
- A laptop behind your back is a magnet for your back.
- No clicker app from an advert.
- Arrow back once, so you can also return a slide.
- Têns in the examples (Sofie, Filip) are made up. Do not put your number, email or photo on a slide.
