Instructional Ideas

• Have learners work in collaborative groups; a different group member can complete one through three, and then combine information to answer number four
  
• After creating a generalized rule, test it with a self-created example

Classroom Considerations

• Provide pupils with graph paper to graph the functions

Pros

• Includes a sample solution
• Guides individuals in the right direction to make an important conclusion

Cons

• None
