Number Line
This compendium of programs develops and tests students' understanding of the order of integers, decimals and fractions.

The program has 3 separate components: Number Ladder, Find the Number and Number Line

Number Ladder Features
> The user must place randomly generated decimals in the correct order.
> The numbers are placed on a "ladder" after which they may not be moved, regardless of subsequently generated numbers.
> The objective is to complete the task with the smallest quantity of numbers having to be "rejected" due to no space being available in the right places on the ladder.
> The numbers may have from 0 to 3 decimal places.

Find The Number Features
> The user must locate and identify a number to a given degree of accuracy. The user can zoom-in on the number line that it is presented upon.
> The user has complete control over the length of the original, starting view of the number line as well as the accuracy of the randomly generated target number (0 to 3 decimal places).
> At each stage of zooming-in, the user can opt to have their understanding checked of where they are on the number line.

Number Line Features
> The user is presented with a number line with at least two values marked upon it. They must correctly deduce the value of a separately marked number elsewhere on the line.
> The line may be labelled with either Integers, Decimals or Fractions.
> There are a total of 160 different number lines generating many more distinct challenge questions.
