Thursday: Spot the Hidden Subtasks

"Feeding a fish is just one step," Rocket says. Raven tilts her head. "Is it? Where is the food? How much do you give?"

Rocket's eyes go wide. "There are hidden steps!"

Nova shines her light on the fish food. "Small words can hide big jobs," she says. Then the crew plans a lemonade stand together. Let's find the hidden subtasks.

These tasks LOOK simple but have hidden subtasks. List 3 hidden ones for each.
