Final answer:
A lesson plan is essential for a functional skills intervention session, which outlines the structure of the session, including objectives, materials, and activities.
Step-by-step explanation:
For a functional skills intervention session, it may be necessary to create a lesson plan. A lesson plan is a detailed guide that outlines the structure and essential features of an instructional session. It often includes objectives, materials, activities, and assessments to facilitate learning. The creation of a shopping list, phone directory, or weather forecast would not typically be part of preparing for an educational session unless they are directly related to the lesson's activities.
