Clap, Clap, Repeat!

Learning Objectives Identify a repeating pattern in a set of instructions. Define a 'loop' as a way to repeat actions. Use a 'repeat' block to make an action happen multiple times. Count how many times an action should be repeated. Create a simple sequence of instructions that includes a loop. Explain why loops are useful for computers. Have you ever sung a song where you repeat the same part? 🎶 Like 'Row, row, row your boat'? Today, we will learn how to tell a computer to do something over and over again. This is called a loop! It helps us give instructions much faster. 💨 Real-World Applications A blinking light on a toy 💡 The chorus of your favorite song 🎤 Waving goodbye many times 👋 Stomping your feet to a beat 🥁

TermDefinitionExample Action Step 👟A single instruction or thing to do.An Action Step could be 'jump once' or 'draw one star ⭐'. Sequence ➡️A list of Action Steps in the correct order.First, pick up a crayon 🖍️. Second, draw a circle 🔵. Loop 🔁A special instruction that tells the computer to repeat Action Steps.Instead of saying 'clap, clap, clap,' we can say 'repeat clap 3 times'. Repeat Block 🟪A block that holds the actions you want to do again and again.We put the 'stomp foot' Action Step inside a Repeat Block. Count 🔢The number that tells the loop how many times to repeat.If the Count is 4, the loop will do the action four times.

The Repeat Rule Repeat [Count] Times { Action Step } Use this to do the same action more than once. Put the action inside the Repeat Block and set the count. The Order Rule Actions happen one after another. A computer follows your steps in order, even inside a loop. It finishes the loop before moving on.
