Instructional Ideas

• Have a discussion with the class to point out that the term function here does not have the same meaning as the term function has in their math class
• Have class members create their own designs using the functions they created

Classroom Considerations

• Even though pupils work in pairs, be sure they know they are each responsible for their own programs
• The fifth in a series of 10 lessons

Pros

• The lesson plan highlights a misconception that individuals tend to make when defining functions in JavaScript
• Contains a link to the forum, so you can get hints from other teachers

Cons

• Challenges five and six can be confusing, leading individuals to think they should draw the entire diamond
