TeacherLED is a website that provides interactive whiteboard resources for educators.

Description

Number Line is an interactive whiteboard resource that allows you to scroll along the number line by dragging the bottom bar.  Give it a flick and the physics will help get you to where you want, taking the chore out of a long scrolling number line.  This can also be used to select a random part of the number line as it will bounce back when it gets to the end.

Two number lines can be on screen to assist with teaching functions and number mapping.  The instructions can be selected by the teacher to give the class a visual reference when taking part in class questioning.  The number lines can be annotated with the built in screen writer and they will move along with the number lines.  Tap on an annotation to remove it click clear to remove all of the annotations.  Use the 1 or 2 button to select whether to show 1 or 2 number lines.

This is resource is as much an attempt to gauge how popular the physics driven interface on the IWB is as anything else.  It seems more natural to have real world responses on an interface you can drive by touch.  Think how you would find a country on a large globe.  Please leave comments and suggestions about the resource and regarding how you found the interface on an IWB.
