This activity has been made for special education classes for the purpose of including the general education curriculum. This activity includes slides designed as a guided writing activity (graphic organizer) that provides sentence starters and response options for completion. It is designed for students to complete on the computer, but can be easily adapted to be completed once printed out. In this activity the students will write a five sentence paragraph (including a topic sentence, three supporting sentences, and a closing sentence) to tell how the Tigris and Euphrates Rivers helped Mesopotamia. Picture supports are included.
