Classroom Toolkit
Single-file selector, groups, and timer

Classroom tools in one page.

Built for your 3-by-8 room layout: mark who is present, spin a 5-second student selector, create random groups by number of groups or by group size, and run quick class timers with one-tap presets, extra time buttons, and an end alarm.

Student selector

Your seating chart is already laid out as front row 1–8, middle row 9–16, and back row 17–24. Click seats on or off for attendance, then run the rotating picker.

Random groups

Use the same present-student list to break students into groups. Choose either how many groups you want or how many students per group, and it will balance the rest automatically.

Class timer

Start 5, 10, 15, or 20 minutes in one tap, pause or reset when needed, and add 1, 2, or 3 minutes on the fly.

Quick use

Start on the Selector & Groups page, click any absent seats, then spin the picker. When you want collaboration, build groups from the same present list. The top navigation always brings you back here.

Student Selector & Group Builder

Click a seat to toggle present or absent. The seating chart is displayed as seen from the back of the room: front row 1–8, middle row 9–16, back row 17–24.
