Instructional Ideas

• After watching the video have the class brainstorm ways that parameters could have helped with some of the previous tasks
• To reinforce the naming of the parameters, have class members share the names for the parameters used in their functions

Classroom Considerations

• Create function cards with parameter blanks to help pupils remember the format of the parameters in their functions
• The eighth lesson in a series of ten

Pros

• The teaching tips provide a suggestion on where it might be a good spot to bring the class back together before moving on to the rest of the lesson
• The Under the Sea tasks build upon each other to highlight the importance of parameters within functions

Cons

• A few of the sentences in the teacher overview are a little awkward but not enough to effect the lesson
