Decimal number line (version 0.5)

What is it?

Decimal number line is an interactive teaching program (ITP) which allows you to select an interval from a given number line and show that interval as a second number line divided into ten equal parts but on a bigger scale. This can then be repeated to create a third number line that represents an interval on the second number line. Initially the ITP shows a number line spanning 0 to 100. This can be adjusted to show intervals of different lengths with different starting numbers.
