Whiteboard

Supported: PNG, JPG, GIF, WEBP and other common image files. Uploaded images can be moved and resized on the board.

Each tool appears on the whiteboard as a movable widget, so you can drag and resize it like other objects.

This tray is part of the whiteboard interface, not an object on the board. Choose a colour and quantity, then place counters directly onto the whiteboard.

Each counter is its own movable object. Double-click a counter to cycle its colour.

Choose blocks here and they are placed directly on the board. There is no extra settings object to delete afterwards.

“Build” creates the matching hundreds, tens and ones as separate movable blocks so students can regroup them.

Click inside an area to fill it. Marker lines act as barriers, so colour stays on the side you clicked. Tiny breaks between marker endpoints are treated as closed to help prevent leaks. You can still click shapes, text or widgets to recolour them.

Draw anywhere with a mouse, finger or stylus. Closing this menu keeps the marker selected.

Rub over any marker line, shape, emoji, text, image, fill or placed item. Only the part beneath the circular eraser is removed.
