1 A longitudinal view of a learnerâs work paints a picture of growth, progress, and continuity over time that the learner can collect, select, and reflect upon to present a profile of accomplishment based on evidence. Create digital evidence of the multiple intelligences of an individualâs growth over time. 2  Develop a personalized profile of achievement, whether as an undergraduate, graduate, or post-graduate student, or a trained professional.
The Tigris is one of the two main rivers of Mesopotamia (modern Iraq). The Tigris is the river to the east (towards Persia [modern Iran]); the Euphrates, to the west. The Tigris runs from Lake Hazar, in the Taurus Mountains, in Turkey, joins the Euphrates, and flows into the Persian Gulf. The Encyclopedia Britannica says the Tigris is 1,180 miles (1,900 km) in length.
In this lesson we explore the Tigris River and its impact on history. Along with its sister channel, the Euphrates, the Tigris fostered the growth of some of humankind's earliest civilizations in Sumer and Mesopotamia.
