A numberline that shows negative numbers for the interactive whiteboard. It ranges from -50 to +50. The numbers are categorised by colour with negative numbers underscored by red, and positive by black. Which isn’t particularly asthetically pleasing but does reflect the financial phrases of “in the red” to represents debt etc.
You can annotate dirtectly onto the line using the built in writing tool. These annotations will then scroll with the line as you move it about. Scroll the numberline using the bar at the bottom. It has realistic physics built into it so the line can be quickly flicked from one end to the other.
This resource could be used in conjunction with this Temperature Comparison IWB resource for teaching negative numbers.
