Scale Whole Numbers on a Double-Sided Number Line: Part I 5-84

Use double-sided number lines to visualize and scale whole numbers proportionally. If it rains 9 inches in 2 months, how much will it rain in 12 months? Multiply or divide to find the scale factor. Since 6 x 2 months = 12 months, it will rain 6 times as much. It will rain 6 x 9 inches = 54 inches in 12 months.
