Sandwich
A sandwich is four moves in the right order: butter first, then topping, then close, then maybe cut. Skip the butter and the rest goes sticky. The visual support below keeps the order for the fingers.

About this visual support
A sandwich looks like one thing but is really a piece of motor choreography. Butter has to go first or the bread soaks up the moisture from the topping. The knife needs to be held so the thumb steers the direction rather than just squeezing. The bread has to be turned so the crust does not catch the blade. Plenty goes sideways when one step lands in the wrong order or is missing entirely.
With each move as its own picture the chain becomes visible. The child can check the image, do that step, check again. The small pause between images is often enough for the fingers to catch up, which matters for children who hurry too much or stall halfway through.
A concrete tip: lay everything out on the counter before you start and let the child match each item to the right picture. That turns the prep into a small game with the topping before the knife appears, and the building itself goes more calmly. In the Routined app you can save your household's most common sandwich combinations as their own schedules.
