Random placement rules
Choose students who must sit at the front (sight, hearing, focus) and pairs to keep apart. The draw tries hundreds of arrangements and keeps the first that meets every rule; if that's impossible, it tells you. Draws use the browser's cryptographic randomness.
Teacher's view or students' view?
The teacher's view draws the room as you see it from the board: the front row is at the bottom and the class's left is on your right. The students' view puts the board at the top, like an architect's plan. Pick a view before printing.
What about privacy?
Student names stay in your browser: nothing is sent, and there is deliberately no share link. Export the class to a file to open it on another computer.
How to use it
- Describe the room: rows of single desks, pairs or threes; group tables of 4 to 6 for group work; or a U-shape for discussions and languages.
- Paste the class list, one student per line, from your spreadsheet or school system. Separate columns (first name, last name) are joined automatically.
- Place students: at random, alphabetically, or by hand by dragging a name onto a seat (on a tablet, tap two seats to swap them).
- Add rules if needed: students at the front, pairs to keep apart. A warning appears if a manual arrangement breaks them.
- Print the plan in landscape, from your view at the desk or the students' view for display, with the list of students and their seats.
Which layout?
- Rows facing the board: teacher-led lessons, tests, large classes. Desks of two make it easy for neighbours to help each other.
- Group tables: group work, investigations, carousel activities. Angle the tables so nobody has their back fully to the board.
- U-shape: discussions, languages, meetings; everyone can see each other and the teacher moves around the middle.
Tips for a plan that works
- Put students who need it at the front (sight, hearing, support plans, focus) before running the random placement.
- Change the plan every half-term: new neighbours refresh discussions and break up established chatter.
- Keep a copy in your planner or for a cover teacher: names are then easy to find.
- To form groups or pick a student at random during the lesson, use Spinoo.
Several classes
Each class has its own plan, saved in your browser. “Duplicate” makes a copy so you can try another layout without losing the current one. Export a class as .json to open it on the staffroom computer.
