Kavi's Big Birthday Cake

Kavi wanted to bake a birthday cake for Grandma Owl — a big task! "Where do I even start?" Kavi hooted. Then Kavi remembered the trick: break the big task into small steps, and put them in order. "First mix the batter. Next pour it in the tin. Then bake it. Last, add the icing." Kavi grinned — "But the order matters! I can't ice a cake before it's baked!" One ordered step at a time, the big task got done. Breaking a big task into small steps in the right order is how clever coders — and clever bakers — win every challenge.
