What is Mathematical Modeling?
A model for thinking about a mathematical concept refers to any object, picture, or drawing that represents the concept.
- To see a concept in a model you must have some relationship in your mind to impose on the model.
- Models give children something to think about, explore with, talk about, and reason with.

The official ratio of the Fly(length) to Hoist(width) of the rectangular flag of the United States of America is 1.90 to 1.00 as set by Executive Order 10834. There is a list of eleven permissible specific flag sizes (specified by length and width) for flags displayed over government agencies: 38.00 × 20.00; 19.00 × 10.00; 17.00 × 8.95; 11.00 × 7.00; 9.50 × 5.00; 5.50 × 4.33; 6.65× 3.50; 4.00 × 3.00; 5.70 × 3.00; 4.50 × 2.37; and 2.50 × 1.32.
How many of these 11 flag dimensions are in the official 1.90:1.00 ratio?
