What high school teachers actually project

Older students ignore decoration, but they watch the clock closely. A useful high school board answers four questions without you saying a word: what are we doing, why, how long do we have, and where is the material.

Add a document camera view when you model problems by hand. The Webcam widget shows a live camera feed on the board; turn Mirror Mode off so writing reads the right way round when the camera points down at paper.

Most high school teachers settle on three or four widgets and change only the text each day. That consistency is the point. When the clock is always top right and the objective always top left, students stop asking.

Block schedule board

A 90-minute block needs more structure on screen than a 50-minute period, because students lose track of where they are in the lesson. The fastest start is the Classroom Agenda template, which opens with an agenda text box, a clock, a 30-minute timer and a job picker you can repurpose.

How to build a block board in 10 minutes

1. Open the Classroom Agenda template and replace the sample agenda with today's chunks.
2. Add a Timetable widget. Type one line per chunk in the form 9:05 | Warm-up. The widget highlights the chunk that matches the computer's clock.
3. Use 24-hour times for afternoon blocks, such as 13:30 | Lab. The Timetable reads 1:30 as early morning, so the highlight would be wrong.
4. Add an Objectives widget with one "I can" statement per line. Tick each box during the lesson so the line is crossed out.
5. Open the screens drawer and press Add New Screen twice. Use screen 1 for the opener, screen 2 for work time and screen 3 for the close.
6. Press Save Board and name it by course and day type, such as "Chem A-day".

Example: a 90-minute chemistry block

This is an example of how a teacher might lay out one block. Adjust the minutes to your bell schedule.

For topic-heavy courses, the Topic & Task Organizer template is a good second option. It already holds a unit title, an objective, key vocabulary, a timer, pairs from the group maker and a QR code.

Block teachers often keep a short movement or stretch break at the midpoint. A transition with a visible timer and one clear instruction tends to run faster than a spoken one; Edutopia's guide to transitions has practical routines worth borrowing [1].

Exam timers and quiet work

During a test, the board should do one thing: show the time left, large and calm.

Which timer to use

• Timer is the quiet choice. Use Set Timer, start it, and it shows "Time's up!" at zero. It is the better fit for tests.
• Countdown Timer has one-tap presets for 1, 5, 10 and 15 minutes, plus buttons to add or remove 30 seconds. At zero it plays a three-note chime and fires confetti. That suits a timed warm-up, but it can startle a room mid-exam. Press Test Sound beforehand so the volume is not a surprise.
• Stopwatch counts up and records laps, which suits labs, speed drills and timed speeches.

A quiet-work board

1. One large Timer, labelled with the section name in a Text widget, such as "Section 1: 45 minutes".
2. Work Symbols set to Silence.
3. Nothing else. Remove games, polls and pickers.
4. Press full screen so tabs and notifications are hidden.

Give spoken five-minute and one-minute warnings as well. Some students do not look up while writing. For standardized exams such as AP, follow the official proctor instructions rather than your classroom routine; the College Board publishes its exam policies [2].

If you need a quiet room for independent reading or test corrections, the same board works with a longer timer. Avoid the sound meter in exam rooms. It needs microphone permission, and a reacting display draws attention.

QR handoffs and review games

QR handoffs

The QR widget turns any link into a code students scan from their seats. Type the address in "Enter URL or text...", press Generate, and resize the code so it scans from the back row.

• Point the code at the exact file or form, not a shared folder.
• Scan it with your own phone before the bell.
• Put the assignment name in a Text widget beside the code.
• Change the code for each section if periods use different forms.

The Exit Ticket template includes a QR widget, a self-assessment poll and a 3-minute timer. Replace its QR link with your own form before using it.

Review games

Short, low-stakes recall is useful exam preparation; retrievalpractice.org collects research and classroom guides on why it works [3]. These widgets make it quick to run:

• Trivia: paste one Question | Answer per line. Show a question, let teams confer, then press Reveal and Next.
• Quiz: one multiple-choice question with up to four options and a set correct answer. Students commit by hand signal before you press Reveal.
• Scoreboard: up to six teams with editable names and plus or minus buttons.
• Quiz Time template: a contestant picker, a 30-second answer timer, rules, a traffic light and a die.

Example: a history teacher might run a 12-minute Friday review with Trivia, four table teams on the Scoreboard and a 30-second timer per question, then switch straight to the Exit Ticket.

When a plain whiteboard is better

• Long worked examples. If you are deriving a proof or balancing equations step by step, a whiteboard or document camera is clearer than text widgets.
• Discussion-heavy seminars. A countdown on screen can make students rush. Keep only the essential question visible, or switch the projector off.
• Assessments you must keep. The poll and quiz show answers on screen but do not store individual responses. Use your learning platform for graded work.
• Shared rooms with locked-down computers. If the browser resets every night, keep board links in your plans and expect to reopen them.

Accessibility for teenage classes

• Size. Resize widgets until the smallest text reads from the back row. Cut words before you shrink fonts.
• Contrast. Dark text on a pale background, or light on Navy, projects well. WCAG asks for at least 4.5 to 1 contrast for normal text [4].
• Colour. Work Symbols use words as well as colour, which helps colour-blind students. Keep labels on any colour cue.
• Sound and motion. Warn students before chimes, and use the plain Timer when the Countdown's confetti could distract.
• Extended time. Students with testing accommodations may need a separate timer. Add a second labelled Timer rather than announcing the difference aloud.

Privacy with older students

• Students never sign in or join with a code. The board is projected only.
• Saved boards stay in your browser's local storage on that computer. There is no account and no sync.
• The Webcam feed shows live on the board and is not recorded. The sound meter reads volume in the browser and does not record audio.
• Use first names in pickers. Never paste student information system exports with ID numbers. Copied links carry the names on the board, which matters under FERPA [5].
