Milk and cereal are a breakfast so common in American households that I doubt few recall the time when they learned about the recipe and procedure to make a bowl of cereal.
In Chile, however, breakfast cereal is still catching on.
Here are photos of the cereal box of a local cereal.
Note the front panel below. You need a bowl and a spoon. The cereal goes in first, and you pour the milk on top.
That image helps, and the side panel offers another hint.
The back panel of the box gets even more instructive.
