Persuasive Writing

My cooperating teacher gave a persuasive writing assignment to our 5th graders. They designed a prosthesis and wrote a "to whom it may concern letter" to a company, trying to sell their product.

The following are taken directly from their letters:
"Do you want these kids to live without an arm? I have something that can make those sad, one armless kids into happy, new armed kids with the Hand Helper 1000.”

“If people buy now they will receive a free tool box. They’ll need it for if [the Hand Helper 1000] gets broken or needs some work. Of course, there is a 50/50 percent chance it will get broken or needs fixed.”

“The Prosthetic Beauty 3000 is stylish, comfortable and full of awesomeness.”

“We will make some deals with you. We’ll throw in an extra Ziploc baggie full of extra nails for each Prosthetic Beauty 3000 you get.”
