Mounted along one classroom wall as a coordinated set. The three-scale framing is INTENTIONAL - it teaches nested scale, a Grade-4-5 expectation introduced at G3. Children practice locating the same school at three scales in lesson 15. Teacher Localization Note: the maps must be locality-specific; templates available from local town/city planning department or USGS for region-scale. The grid system is essential for lesson 14.
