Kavi's Backwards Sandwich
Kavi was hungry! "I'll make a sandwich," said Kavi — and spread the butter before getting the bread. Splat! Butter all over the table. "Oops," Kavi laughed. "A computer does exactly what I say, in the order I say it. If I mix up the order, I get a mess. Let's do steps in the right order, one at a time."

What your child will learn

2Change the order, change what happensA computer never guesses — it just obeys the order. Predict what goes wrong if two steps are swapped, then reveal.
3Steps happen one at a time, top to bottomA computer reads steps one at a time, from top to bottom. Press Run and watch Kavi plant a seed, step by step. Each step waits for the one before it.
