① Surface · Build the knowledge

Phase 1 — Build the knowledge

Before students can reason about how to share the river, they need the raw material: the words, the picture of a region, and the geographic tools. These three activities are fast and front-loaded — the goal is acquisition, not yet analysis.

🎯 By the end of Phase 1 students can use the key vocabulary, describe the four things that make a region (geography, economy, government, culture), and read a simple map and data table to compare how three countries use the river.

1 · Word bank & vocabulary sort

Introduce and let students sort the unit vocabulary. Sort twice: first into “words about the land & water” vs. “words about people & systems,” then by student-invented categories (feedback on their reasoning).

WordKid-friendly meaning
regionan area whose places share features — landforms, climate, economy, or culture
natural resourcesomething from nature people use, like water, soil, or fish
scarcitywhen there is not enough of a resource for everyone who wants it
factors of productionthe four things used to make goods: natural resources, labor, capital, and entrepreneurs
economic systemhow a society decides what to make and who gets it: traditional, command, market, or mixed
governmentthe system that makes and enforces a society's rules: limited (power has limits) or unlimited (power does not)
interdependencewhen people or countries depend on one another
watershedall the land whose rain and streams drain into the same river
hydroelectricelectricity made by moving water, often at a dam
stakeholderanyone affected by a decision or who has something at stake

2 · Jigsaw reading — What makes a region?

Split the class into four expert groups, each studying one topic below, then re-mix into home groups where every topic is represented. Each expert teaches their group. (Jigsaw is one of the highest-leverage surface moves precisely because students must teach.)

🧩 Use the ACE Powered Jigsaw Organizer — experts capture their notes on it before teaching their home group: open the organizer ↗. New to running a jigsaw? See the teacher guides in the facilitator guide.

Sources for each expert group (free, reputable; confirm access through your district — links open in a new tab):

A · Physical geography & climate

A river begins in highlands and flows through a watershed to the sea. Rainfall, dry seasons, and where the water flows decide who has plenty and who has little.

📄 National Geographic · River ↗
📄 NOAA · Freshwater ↗

B · Economy & resources

People turn the river into food (farming), power (hydroelectric dams), and jobs. The river is a natural resource — one of the factors of production — and using it is human–environment interaction.

📄 World Bank · Water (overview) ↗
📄 U.S. EIA · Hydropower explained ↗

C · Government & citizenship

Every country decides its own rules. Governments can be limited or unlimited, and what rights and responsibilities citizens have varies from society to society.

📄 Britannica · Government ↗
📄 CIA World Factbook (government sections) ↗

D · Culture & daily life

Language, food, faith, and daily routines differ from country to country. To solve a shared problem, neighbors must understand one another's culture and points of view.

📄 Nat Geo Kids · Countries ↗
📄 CIA World Factbook · a Nile-basin country profile ↗

Check for understanding: each home group writes one sentence answering “Name one way geography, economy, government, and culture each shape life in a region.”

3 · Map & data work — reading the river region

Project a simple map of a river that begins in Highland (upstream), flows through Midland, and ends in Rivermouth (downstream) before reaching the sea. Students label the river, the watershed, the three countries, and where the biggest cities and farms sit. Then read the data table below — the first move in using geographic tools.

CountryPosition on riverPeople (millions)Main use of the river
HighlandUpstream (source)18Building a large hydroelectric dam
MidlandMiddle32A fast-growing city that needs drinking water
RivermouthDownstream (mouth)45Farming that feeds most of the region

Quick write: “The country of ______ is ______ (upstream/downstream). It uses the river mainly for ______. In a dry year, the country most at risk is ______ because ______.”

📚 Sources: National Geographic · Watersheds ↗ · Our World in Data · Water use & stress ↗

Surface check before moving on: can every student use the words watershed, scarcity, interdependence, and stakeholder correctly, and say which country is upstream and which is downstream? If yes, go deep. If not, reteach — the problem in Phase 3 depends on it.
