Texas Essential Knowledge and Skills for Social Studies

Teacher's field guide

What Students Need to Do: Students identify economic, geographic, and political factors that increased demand for enslaved labor. They connect cash crops, plantation profits, Atlantic trade routes, slave laws, and racism in a clear cause-and-effect explanation.
What Mastery Looks Like: A student can build a cause chain showing why plantations expanded and how that growth increased forced migration from Africa. The student supports each link with accurate historical evidence.
Common Misconceptions: Students may think cotton caused slavery’s first growth in the English colonies, overlooking earlier tobacco, rice, and indigo production. They may also treat enslaved Africans as voluntary immigrants or ignore how laws and racist beliefs protected the system.
How to Assess It: Exit ticket: Draw a three-link cause chain connecting a cash crop, plantation growth, and the expansion of slavery, then explain each link in one sentence.

Lesson moves

Give pairs cards labeled tobacco demand, land, labor shortages, profits, slave codes, and shipping routes; students arrange and defend a cause map.
Write one paragraph answering: How did crop profits, Atlantic trade, and colonial laws work together to expand slavery?
Run a card sort where teams match each factor to plantation growth, slave trading, or slavery’s geographic spread.
Compare a colonial tobacco supply chain with a modern product supply chain, focusing on who profits and how labor is controlled.
