Have a student write out detailed instructions for performing a basic task, then have another student try to follow these instructions exactly. Engaging, interactive classroom activities like this demonstrate that program instructions need to be explicit.

Use algorithm “simulation” activities, where one student writes out instructions that another student must follow.
- Examples of algorithm "simulation" activities include Internet packet passing activities, making a paper airplane, making a snowflake, tying their shoes, putting on a t-shirt, and the PB&J activity.
When you use activities that gloss over details, don’t rush to explain how the details were glossed over.
A lot of care is required to keep this type of conversation focused and productive.
The benefits of student engagement makes using interactive activities that appear to be off-topic worth your class time.
To incentivize this activity, a student’s grade should be based on how successfully their partner completes the task by following their instructions word-for-word.
