"Numerline" is a focused authoring tool, designed with Geogebra 5.0 software, which combines in its interface: a) the funtionality of having multiple partitions of the numberline and setting its limits, b) the funtionality of simultaneous use of physical and decimal numbers, (c) the ability to display more than one numberline at a time and (d) the use of different comparison tools. 
With the numberline template the user can develop interactive activities focusing on the concept of number, position value and arithmetic. 40 microexperiments have been developed with the Numberline template and they are mounted on the the Photodentro National Repository.
