The ClassDa.sh board: a class of animal tiles in the middle, today's schedule on the left, tools on the right.

Your class

  • Every child on a tile with a drawn animal, A–Z or by seating chart.
  • Positive-first points: +1 a child, a table, a group or the whole class, with a class goal to fill. A −1 is logged quietly with a reason and never shown on the board.
  • Attendance, a bathroom pass with a line, and who's out of class.
  • Pick a name, make groups, line up, class jobs.

Your day

  • Today's bell schedule, big enough to read from the back, with the next period counting down.
  • A learning target from your state's standards, one tap to put on the banner.
  • Today's weather, and “Day 46” of your school year. Tap the clock for the week ahead and countdowns, or the weather for the hours and the week ahead.
  • Lessons with timed plans, slides and assignments, kept in a library, and Notes to show a line big.

Quick tools

Timers (up to four), stopwatch, think-pair-share, dice, a coin to flip, a spinner and a random number, a traffic light and noise meter, voice levels, focus and rest music, breathing, a whiteboard with handwriting lines and graphic organizers, a calculator, a teaching clock (drag the hands or the digital numbers), sight words and a word wall, and anchor charts for your grade. Each one opens over the class and keeps running when you put it away.

Plus the class's own: jobs that move on every week, a countdown to the next big day, a morning check-in where kids tap their name and their lunch, with the count ready for the office, a secret mystery student, and a Drill button that puts a big headcount on the board (and keeps the board silent) for fire drills and lockdowns.

Built for the board

  • Laptop plugged into the board? Press Present: the board gets its own full-screen window that stays in step with your laptop.
  • Board with its own computer? Save a classroom file and open it there.
  • Made for Chrome and Edge, and keeps working when the Wi-Fi drops.
Getting started

About five minutes

  1. Open classda.sh in Chrome or Edge on the computer connected to your board.
  2. The setup guide asks for your class list (paste it straight from a spreadsheet), your grade and your school's town, then fills in a school year and a bell schedule for you to check. Skip anything you like.
  3. Press Present to put the board on the big screen, or use full screen if the board is your only screen.
  4. Once a week, save a classroom file (Settings → Records & safety) as a backup.

Your class's information

Stays on your devices

There are no accounts. Names, points, attendance and notes are saved in the browser on your own computer, and they are never sent to us: we have no database to send them to. The board works offline after the first visit. The whole story, including the few things that do use the internet, is in the privacy policy.

What to allow, and what it does

ClassDa.sh is a static website: plain HTML, JavaScript and pictures, with no logins, no server code and no database. Please categorize it as Education.
