Interactive Power Pole Understanding Positive and Negative Numbers

This interactive exercise allows students to see in real time the logic of positive and negative numbers. It is a real life scenario as a new employee of a power company, they must learn how to set a power pole. By entering the length of the pole in the first column, and how deep of a hole the pole must be placed in as a negative number, the resulting amount is populated in the third column which represents the amont of the pole that will remain above ground. In the chart to the right, students see in real time the actual pole, the amount of the pole above ground represented in blue and the amount underground in brown. This gives kids an alternative way of thinking about positive and negative numbers..instead of the traditional number line method....The app is fun and interactive which in itself brings understanding and remembrance in children.
