I'm unable to create visual diagrams directly. However, I can guide you on how to use the Sentence Diagram Generator to diagram the sentence "Candice and she gave Mr. Phillips, their teacher, some homemade cookies."

1. Input the Sentence: Enter the sentence into the Sentence Diagram Generator.

2. Identify the Main Components:

   • Subject: "Candice and she"
   • Verb: "gave"
   • Indirect Object: "Mr. Phillips"
   • Appositive: "their teacher"
   • Direct Object: "some homemade cookies"

3. Diagram Structure:

   • Start with the main horizontal line for the subject and verb.
   • Branch out for the compound subject "Candice and she."
   • Draw a vertical line for the verb "gave."
   • Extend a line for the indirect object "Mr. Phillips."
   • Add a line for the appositive "their teacher" connected to "Mr. Phillips."
   • Finally, extend a line for the direct object "some homemade cookies."

Using these steps in the Sentence Diagram Generator will help you visualize the grammatical structure of the sentence effectively.
