Building on the concept of repeating instructions from Getting Loopy, this stage will have students using loops to more efficiently traverse the maze.
Activity: Maze Loops
- Identify the benefits of using a loop structure instead of manual repetition
- Create a program for a given task which loops a single command
- Break down a long sequence of instructions into the smallest repeatable sequence possible
- Create a program for a given task which loops a sequence of commands
- Employ a combination of sequential and looped commands to reach the end of a maze
Review with students the Getting Loopy activity:
- What are loops?
- Why do we use them?
As students work through the puzzles, see if they can figure out how many fewer blocks they use with a loop vs. not using a loop.
- Give the students pictures of actions or dance moves that they can do.
- Have students arrange moves and add loops to choreograph their own dance.
- Share the dances with the rest of the class.
Connect It Back
- Find some YouTube videos of popular dances that repeat themselves.
- Can your class find the loops?
- Try the same thing with songs!
