resource room teacher
I just finished a lesson with my 5th grade resource students where we had to write persuasive letters. First, they had to write a letter to me persuading me NOT to give them homework for the long weekend off.
Ihad them create webs where the main goal was in the middle (to persuade teacher not to give HW). Then off of that they were to put three boxes. These were three main reasons why they should not have homework. Ex: Want to spend more time with family.
Then off of the boxes, they were to try to put one or two circles which gave more details about their reasons. Ex: from the above reason: family barbecue on Saturday or Sister's birthday party, etc.
Using this information, they wrote letters to me. Other topics might be:
write a letter persuading your parent(s) to let you adopt a pet or to spend time over the vacation doing a special activity. One boy wrote a letter asking his parents to take the family on a campout and they actually are going.
Just some ideas. Hope this helps a bit.
