4 December - 10 December

EXPLORE / TŪHURA learning intentions:

• We are EXPLORING the spatial distribution of different types of geographical phenomena by constructing maps at different scales.
• We are INVESTIGATING maps to identify direction, scale and distance, area and grid references, latitude and longitude, altitude, area, contour lines, gradient, local relief

Students will recognise differences between large-scale and small-scale maps.

Engage 
What is map scale? 
 To start the map, click the map URL link below. 
? What is map scale? 
? What is a large map scale? 

Explore 
How do features change at different map scales? 
 Press the home button on the map. 
 Using the scale bar in the bottom left of the map, read the scale. 
The scale may read 1cm equals 500km
? 
What is visible in this image? 

  Zoom in to view New Zealand.
? 
What new features are visible now that were not visible in the worldview? 

 Continue to zoom in to the following locations: 
o Auckland 
o Flat Bush 
o MHJC

What new features are visible in each image? 

Explain 
How do we determine large scale versus small scale?
At what scale did the Region boundaries? 
At what scale are buildings and houses clearly visible on the map? 
Would a scale of 1 cm to 1 km be considered a small-scale or large-scale map? 

Elaborate 
How are maps measured?
Is a map showing directions from school to the nearest town centre a large-scale map or a
small-scale map?
Is a map of Waikato River system a large-scale map or a small-scale map?

 Click the button, Measure. 
Select the Distance button, and from the drop-down list, choose
kilometres.
What is the straight-line distance between Auckland and Wellington?
Does the measured distance (using the Measure tool) match the distance when using the
scale bar?
