Purpose: 

Riley’s: To convince my mom, Myra that crystals are better than diamonds.

Myra’s: To convince Riley that diamonds are better than crystals.

Examples:

Riley: I think crystals are better than diamonds because they look more natural with the crooked edges. I have a crystal that has natural crooked edges.

Myra: My favorite precious stone is a diamond because it is rare and very durable for jewelry.  Durability is an important quality for me because I don’t want it to break when wearing it!

 

Riley: You can find crystals in rocks easier than you can find diamonds in rocks. When I went by the rocks I found a crystal and I have never found a diamond.

Myra: I like how diamonds sparkle and comes in many colors.  When the sun hits the diamond in a certain way, it sparkles.

Conclusion: 

Riley: Did I convince you?              

Myra: Yes

Myra: Did I convince you?

Riley: Yes
