Division is the multiplication rectangle, cut. Start with the whole block — every dot touching — then cut it and move the pieces apart. The answer is how many pieces you made. Record it, or stop on a step and screenshot the frame straight onto a card.
Hide controls gives you a clean stage to screen-record. Click the stage again to bring them back. Each set takes the next number-line color — first red, then orange, yellow, green, blue, purple — so you can read how many sets there are off the colors without counting them. If you picked your own colors on the Games page, this page uses them.
