Ten tools for during the lesson.

Enter your class once. The picker, the groups, the seating chart and the register all use it. No account, no ads, and nothing leaves this browser.

Name pickerPicks without repeating, and skips anyone marked absent. GroupsEven groups, with keep-apart pairs the class never sees. TimerAdd a minute mid-run. Loud, soft or silent. SeatingA printable grid in one click. No trial, no watermark. NoiseAmplitude, not fake decibels. Nothing is recorded. RubricCriteria down, levels across, printed. GradesYour boundaries, and how far off the next band is. RegisterTap to mark absent. Every tool then skips them. DiceUp to eight dice, and the total shown large. StopwatchCounts up, correct even in a background tab.

One class list, every tool

The most common complaint about the tools teachers already use is retyping the class every morning. The three products that avoid it all want an account, and the free tier of the most popular one stops at three classes.

Here the list is typed once and shared by every tool that needs names. Mark someone absent on the register and the picker skips them, the group generator leaves them out, and the seating chart does not save them a chair.

Built for a projector, not a laptop

Everything a room needs to read is set as a proportion of the screen rather than a fixed size, so it keeps growing on a big display instead of stopping at a comfortable desk size. Contrast is set well above the usual accessibility floor, because daylight and a projector's black level wash out anything subtle.

Every tool has a presentation mode that removes the toolbar and goes full-screen. On a 1024 by 768 projector, browser chrome alone takes a fifth of the screen.

No ads, and why that is not only about taste

Most free classroom tools carry advertising, including in full-screen. A survey of over six thousand teachers found more than half had seen inappropriate or unsafe advertising while streaming content in class. Whatever the revenue argument, a slot on the board at the front of a room full of children is not a good place to hand control to an ad network.

It also keeps the privacy position simple. Nothing is collected, so there is nothing to disclose, share or lose.
