I build free classroom tools at lans.cloud, and every August the same pattern shows up in the inbox: teachers setting up a new room, asking whether this or that arrangement "actually works." So before the new year starts, here's the setup guide I'd want — the three decisions you make before the first bell (seating, jobs, routines), what the research genuinely supports for each, and where it's honestly just accumulated practitioner wisdom. Plus the free tools, because that's my trade.
Everything linked below is free, needs no account, and runs entirely in the browser — student names never leave the device, which matters more in a school context than most edtech marketing admits. The whole set lives at lans.cloud/classroom-tools.
Seating: let the task pick the layout, not the Pinterest board
The best-evidenced thing anyone can tell you about seating is also the least dramatic. Wannarka and Ruhl's 2008 review in Support for Learning pulled together the empirical studies comparing common arrangements — rows, groups, semi-circles — and the headline is: the task should dictate the arrangement (Wannarka & Ruhl, 2008). Students showed more on-task behaviour during individual work when seated in rows; group arrangements earned their keep during collaborative work. And the students who benefited most from rows during independent work were exactly the ones teachers worry about — the easily distracted and frequently disruptive.
Two practical consequences for September. First, don't pick "your" layout in week one and defend it all year — plan to re-arrange when the dominant task type changes, and tell the class that's normal. Second, the disruptive-student finding cuts against the common instinct to break up rows because they look old-fashioned: if your class struggles with independent work, rows are the evidence-backed starting point, not the failure mode.
The part research can't do for you is the constraint-solving: keep those two apart, that one needs to be near the front, these three can't share a pod. That's the fiddly bit I built the seating chart generator for — paste your class list (straight from Excel works), pick rows, pods or a horseshoe, add keep-apart pairs and front-row pins, and it generates arrangements that respect every rule, tells you honestly when your rules are impossible, and prints. Reshuffling mid-term takes one click because the roster and rules are saved in your browser.
Classroom jobs: distributed ownership, honestly framed
I'll be straight: I couldn't find a rigorous effect-size literature on classroom job charts the way there is for seating, and I'm not going to invent one. What jobs are is a well-loved application of two sturdy ideas — giving students genuine responsibility for their shared space, and taking recurring low-level decisions off the teacher's plate. Every experienced primary teacher I've heard from treats the job chart as load-bearing routine infrastructure, and the failure mode they describe isn't "jobs don't work," it's "the chart died in October because rotating it was annoying."
So the design goal is a chart that survives contact with the school year: rotation you don't have to think about, and absence handling that doesn't collapse the system the first time the line leader is out sick. That's what the classroom jobs chart generator does — set up jobs and students once, rotate fairly with a click, handle absences without losing anyone's turn, and print the week's chart for the wall.
While you're doing wall displays: a birthday chart is the five-minute version of the same belonging idea, and the birthday chart generator makes a printable one from a pasted list (it handles the same-day twins case that breaks the hand-drawn version).
Routines: the unglamorous week-one investment
The practitioner consensus here is old and stable — Harry Wong's The First Days of School made "teach procedures before content" the standard advice decades ago, and whatever you think of the book's style, the core claim has aged well: the classes that run smoothly in March are the ones that rehearsed transitions in September. Routines are also where a couple of small tools quietly earn their place on the smartboard:
- Transitions with a visible countdown. "Three minutes to pack away" works better when the three minutes is a shrinking bar everyone can see — especially for the students who struggle most with time estimation (I went deeper on that research, with the ADHD time-blindness literature, in an earlier post). The classroom timer is fullscreen and ad-free for exactly this.
- Fair turn-taking from day one. Seed the random name picker with your class list during setup week and cold-call fairly from the first lesson — the "no hands up" rationale is in that same earlier post.
- Volume expectations set with the class. Decide your working-volume zones together in week one, then let the noise meter do the nudging instead of your voice. Audio is analysed in the browser and never recorded or uploaded.
- One board for the daily kit. If you'd rather have the timer, picker, date and a sketch pad on a single smartboard screen, that's the classroom screen.
The September checklist
If you want the compressed version: pick a seating layout for your dominant task type and build the chart with your actual constraints; set up jobs with a rotation you'll actually maintain; and spend week one rehearsing transitions with a visible timer while the routines are still cheap to change. Layout, ownership, rhythm — in that order.
None of these tools need installing or approving, none ask students to log in, and nothing leaves the browser — the privacy write-up for schools is at lans.cloud/for-schools if someone in leadership asks. And if there's a setup-week tool you wish existed, tell me: the seating generator's keep-apart rules, the jobs chart's absence handling and several other features exist because a teacher asked for them.
