Instructional Ideas

• Have the class work in pairs
• Provide pupils with an enlarged copy of the counties so they can dissect and recompose the figures into rectangles

Classroom Considerations

• Learners need to be able to calculate areas of different types of figures

Pros

• Pre-activity reviews concepts and skills necessary for the task
• Teacher guide includes rubric and complete answer key

Cons

• Although the resource provides a lot of information about pesticide spraying, it does not draw any actual conclusions
• The two parts of the task are disjointed and not related to each other
