I have this question on a homework

assignment. PLEASE HELP!!

Mr. Eller wrote the following steps on
individual cards:
1. crush graham crackers
2. put pudding in the cup
3. sprinkle crushed graham crackers
on pudding
4. Add a marshmallow and enjoy!
He mixed up the cards and had the
children put them in order and follow the steps. Which was he teaching?
1.seriation, 2.grouping, or 3.temporal ordering

Is this an example of seriation?

I think he was teaching temporal (which means time) grouping. He wanted the children to figure out the correct temporal order for doing this task.

Seriation is arranging items in order, usually time order.
