Before students can solve the river problem, they need the raw material: the words, the facts about how people live with nature, and how to read a map. These three activities are fast and front-loaded — the goal is acquisition, not yet analysis.
Teach the unit words. Then let students sort them twice: first into "words about nature" vs. "words about what people do," then into their own groups (give feedback on their reasoning). Keep the words on the wall — the whole unit uses them.
| Word | Kid-friendly meaning |
|---|---|
| environment | the land, water, air, plants, and animals around us |
| natural hazard | something in nature that can hurt people or places (a flood, a storm) |
| flood | when water rises and covers land that is usually dry |
| adapt | to change what you do to fit the land (build higher, move away) |
| modify | to change the land to fit people (build a wall, dig a channel) |
| conserve | to protect nature and use it with care |
| levee / wall | a long wall or raised bank that holds a river back |
| wetland | low, soggy land near water that soaks up floodwater like a sponge |
| erosion | when moving water slowly wears away soil and land |
| budget | a plan for how to spend and save money |
| stakeholder | anyone who is affected by a decision or has something at stake |

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 because every student must teach.)
Sources for each expert group (free, reputable; confirm access through your district — links open in a new tab):
Rain and melting snow make a river rise. When the water rises too high, it floods the land nearby. A flood is a natural hazard.

People change what they do: they move to higher ground, build houses up on stilts, and use flood warnings to leave in time.
📄 Ready.gov · Floods (get ready & warnings) ↗
📄 NWS · Turn Around, Don't Drown ↗
People change the land: they build walls and levees, dig channels, and plant trees or keep wetlands to hold back water.
📄 EPA · Why wetlands matter (soaking up floods) ↗
📄 EPA · Green infrastructure (nature-based ways) ↗
Every choice costs money and has good and bad sides. A wall is strong but expensive; trees are cheaper but slower. People must choose.

Check for understanding: each home group writes one sentence answering "Name one way people ADAPT to a river and one way people MODIFY the land near a river."
Show students a simple map of Willow Bend with the river running through it. Point out and name the five map elements: title, compass rose, legend, scale, and grid. Then have students find and mark the river, the floodable areas near the bank, and community services — the school, the fire station, the park, and Main Street. Talk about how people change the land to build near a river (§(c)(3)(B)).
Quick write: "On my map, the ______ is at grid ______. It is ______ (use the compass rose) of the river, so it ______ (would / would not) flood."
