Whether you teach a class of thirty or run workshops for adults, you already know what your room needs, you just don't have time to make it. Here are three small tools for the screen at the front of the room. Each one takes one message to start, and you can use it tomorrow.

A group maker that shuffles your class into random teams on the big screen
No more picking teams by hand or hearing "that's not fair." The screen decides, everyone sees it happen, and it works just as well for a room of adults at a workshop.
1. Paste this first message into Claude
Build me a group maker for my classroom screen, as a single HTML file I can open by double-clicking. Use 24 made-up student names for now, shown in a list I can edit. I choose how many groups I want, press one big button, and it shuffles everyone into random groups shown as big colorful cards that are easy to read from the back of the room. Add a button to shuffle again, and a name picker that picks one random student with a short spin. It doesn't need to save anything between visits.
2. Open what it made
Say yes when Claude asks to make the file, then open the .html file it made by double-clicking it.
3. Tell it what to change, for example
“Let me paste in my own list of names, one per line, instead of the made-up ones.”
“Make the names bigger so the kids at the back of the room can read them.”
A self-marking quiz your class can take together on the classroom screen
Instant feedback without a stack of marking tonight. Ask for any topic and age, and it becomes a quick warm-up or end-of-lesson check the whole room can shout answers at.
1. Paste this first message into Claude
Build me a self-marking quiz my class can take together on the classroom screen, as a single HTML file I can open by double-clicking. Make it 10 multiple-choice questions about the water cycle for 10-year-olds, one question at a time, with four big answer buttons. When someone picks an answer, show right away whether it's right in green or wrong in red, with a one-line explanation, then a Next button. At the end, show the score and a list of the questions we got wrong. It doesn't need to save anything between visits.
2. Open what it made
Say yes when Claude asks to make the file, then open the .html file it made by double-clicking it.
3. Tell it what to change, for example
“Change the questions to be about fractions instead, still for 10-year-olds.”
“Make the answer buttons bigger and add a little celebration when we get one right.”
A lesson or workshop timer that walks the room through each stage
You stop checking the clock and the room keeps itself on track. Set your stages once, press Start, and everyone can see what's happening now and how long is left.
1. Paste this first message into Claude
Build me a session timer for a classroom or workshop screen, as a single HTML file I can open by double-clicking. It walks through stages. For now use: Warm-up 5 minutes, Main task 20 minutes, Pair share 10 minutes, Wrap-up 5 minutes, and let me edit the names and minutes. Show the current stage name and a huge countdown, with a bar showing the whole session and where we are in it. Play a soft beep when a stage ends and move on to the next one. Add Start, Pause and Skip buttons. It doesn't need to save anything between visits.
2. Open what it made
Say yes when Claude asks to make the file, then open the .html file it made by double-clicking it.
3. Tell it what to change, for example
“Make the screen turn orange in the last minute of each stage so everyone can see time is nearly up.”
“Add a full-screen button so it fills the whole projector.”
