Order of Operations | Assessment Review
Students review the order of operations by acting out simple coding steps and sequencing actions correctly. They practice reading, planning, and fixing code so a task works as intended.
| Term | Definition |
|---|---|
| order | The way steps are arranged from first to last. |
| sequence | A set of steps in the correct order. |
| code | Instructions that tell something what to do. |
| debug | To find and fix a mistake in code. |
| step | One action in a sequence. |
Say: 'Today we will review how to put code steps in the correct order.' Model a simple example such as: clap, stand, sit. Ask what happens if the steps are mixed up.
Choral response and brief discussion about why order matters.
Show 3 to 4 step cards on the board in the wrong order. Think aloud: 'First, I need to check what must happen before the next step. I will move the steps until the code makes sense.'
Watch, listen, and help reorder the steps.
Give students a short mixed-up sequence to solve together, such as: 1) pick up cube 2) push cube 3) line up cube 4) stop. Ask students to identify and explain the correct order.
Work with a partner to sequence the steps and share answers.
Post one challenging 4-step code sequence on the board. Ask students to write the correct order on their paper or mini-whiteboard. Circulate and prompt with questions like: 'What must happen first?' and 'What step comes next?'
Independently reorder the steps and check their work.
Show one wrong answer and invite students to debug it. Ask for a volunteer to explain the fix using the words first, next, then, last.
Participate in correcting the sequence and explaining the reasoning.
Summarize: 'Good coders put steps in order so the program works.' Ask students to show thumbs up if they can fix a code sequence.
Give a quick self-check response and prepare to transition.
Reinforce that coding depends on correct order. Students leave with the idea that even small mistakes in sequence can change the result.
