Remember: An algorithm is a list of clear steps, in order, that gets a job done. Each step must be small enough for a robot to follow.
Read and answer
Read the story, then answer.
Squish!It is Saturday, and hungry Maya asks Bo to make her a jam sandwich. "Make me a sandwich," she says. Bo does exactly what he heard, so he puts the jam on the bread. Squish! The whole jar goes on top. Jonah bursts out laughing. Maya sighs that make a sandwich is not enough for a robot. So she writes each step on a card: take two slices of bread, take the lid off the jam, spread jam on one slice, and press the slices together. Each card has one clear job. Bo follows the cards one at a time, and this time the sandwich is perfect. Maya says her cards are an algorithm.
