Exporation of Scale Models
Use tiny toy cars, trucks, tractors, Mars Rover, Space Shuttle, doll house furniture, and a globe to represent "scale models" of large objects.
Using different units of measurement: (plastic links, large and/or small paper clips, unit blocks, Unifix cubes, rulers, tape measures, string), students measure the scale objects and the objects they represent if any are handy. ( Example: cars in the parking lot, chairs, tables etc.)
Discuss how they are different in size from the objects they represent.
