Turn a map measurement into distance
Use a supplied scale without confusing a map with real travel conditions.
Open lesson 1Maps as Decision Models
Combine scale, coordinates, conditional time estimates, and explicit route criteria.
Before you begin
- Multiply and divide distances; read signed integers; distinguish a measurement from an assumption.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
Follow the lesson sequence
Interpret a Local Coordinate Model
Read signed fictional coordinates and keep the model distinct from latitude and longitude.
Open lesson 2Make a Conditional Travel-Time Estimate
Use a supplied rate while stating the limits of a model.
Open lesson 3Compare Routes by Stated Criteria
Choose a paper route under explicit criteria and report missing facts.
Open lesson 4Review and transfer
After the lessons, try 4 new review cases and a practical task. Each answer has an explanation and a link back to the related lesson.
