What This Standard Means

What Students Need to Do

Students read the legends, scales, and dates on historical maps and current digital maps. They compare where rivers, flooded areas, and neighborhoods appear, then explain how the river and land use shaped past flooding and present risk.

What Mastery Looks Like

A student can identify a pattern on two maps of the same area and support a claim with evidence from each. They can explain that a historic flood map shows where water went, while a current risk map shows where flooding may occur.

Common Misconceptions

Students may treat a historic flood area and a current flood-risk zone as the same measurement. They may assume every place near a river floods or overlook changes in levees and development.

How to Assess It

Give students a 1927 Mississippi River flood map and a current FEMA flood-risk map of the same stretch. Ask them to mark one overlap and explain one reason present risk might differ from the 1927 flood area.

Ways to Teach It

  1. Give pairs transparent sheets to trace flooded areas on a 1927 Mississippi River map and risk zones on a current FEMA map.

  2. Ask students to write: Why might a town flooded in 1927 face different flood risk today? Use evidence from both maps.

  3. Give teams river, elevation, flood-risk, and housing maps; have them choose two that best explain a marked neighborhood's risk.

  4. Open FEMA's flood map for a river town and a street map, then circle roads that cross mapped flood zones.
