I have a book I purchased when I was homeschooling my daughter. It gives instructions for the parent to read out, for the child to follow. The results of the instructions are a picture drawn by the child. (half the instructions allowed creativity by the child, with a few guidelines)
I showed it to a friend, and, like me initially, she read a sample of it, and tried following along. Reading one sentence at a time, and sometimes she had to rework out how the instructions led to each other.
When she finally understood it, I picked a random instruction set, and read them out to her, a little at a time. She got frustrated a few times, but we got through it.
Then I had her read me a random instruction set. And she got frustrated watching me as I tried to work out what the instructions meant. (the reader had an image to aide the reader in understanding what was being asked for)
This allowed her to actually experience what it was like to receive the instructions, as her daughter would, and to give the instructions while knowing ahead of time what's meant. Both sides were filled with frustration.
Then, to make a further point, I had her imagine a picture she'd want me to draw, and to give me instructions one step at a time. She found this much harder, of course, than reading. Through my following her instructions, she got feedback as to how often she skipped steps, or skipped relevant info needed, or how what she said could be interpreted multiple ways, etc.
Then, I gave her instructions of my own. And she got to experience how frustrating it is to work with incomplete instructions.
The point of this experience, as I told her, is that now she has a better understanding of what her daughter goes through when she's given a full list of instructions all at once, and expected to follow them to the letter at a later time.
