Generating a Map Legend
Before assigning a mapping exercise as homework, there is a need to establish a method that students will use to devise symbols for the Map Legend. Explain the following things.
A map legend is a collection of symbols needed to read a map.
A symbol is an object which stands for something else.
It can be a picture or drawing, a shape, a letter, or a number.
On a map, all of the symbols are collected together to form the Map Legend. Usually the map legend is a space where symbols and their meanings are defined. Sometimes this map legend is located at the bottom of the map.
The secret to using a map successfully is to create and explain the Map Legend successfully.
Before students draw a model, or map of The Block, (or neighborhood, or home), they will need to determine what symbol will stand for each item on the map. Designing a Map Legned will help you to "read" the map.
Look at some sample symbols which could be used in the Map Legend. Use a worksheet or overhead transparency to show individual sample symbols.
At this point, the class could devise common symbols to be used in each individual's mapping exercise, or, students can devise their own.
If students devise their own symbols and Map Legend, the need for a set of common symbols becomes evident when the individual maps are displayed.
This will motivate students and set the purpose for a lesson in congruent/uniform legend symbols.
Student Sheet:
A symbol is an arbitrary (this means you decide) object which stands for something else. It can be: a picture or drawing, a shape, a letter or a number. Anyone can use or "read" the symbols you create as long as you tell them what they stand for. On a map, these symbols are called the Map Legend. They usually appear at the bottom of the map. It helps someone else to read the map. You are going to create a Map Legend. Make your symbols very simple.
