Free browser tools built for the projector: spin-the-wheel picker, random name picker, team generator with skill balancing, countdown timer, and a seating chart generator that can keep specific students apart. The difference: every tool has a genuinely ad-free fullscreen presentation mode. No banners on the smartboard, no popups mid-lesson. No sign-up, nothing uploaded — class lists stay in your browser. You can even embed the wheel or timer directly into your class website.
