Shape fractions
Fractions are represented by creating equal-sized regions within a two-dimensional shape, and naming these parts using words and numerals in fraction notation. The student divides simple shapes into equal parts. They can select regions, then express the area selected as a fraction (or equivalent). Students also select fractions or choose other options to set variables displayed.

Dynamic fractions
This shows the direct relationship between the spatial, symbolic and written representations of a fraction. The alternative representations change dynamically, emphasising the equivalence between the various representations. There are three modes of display and interaction:
Mode 1: Grid that the user can set between 1 and 10 in each of the text fields.
Mode 2: Grid with number line, including fractions.
Mode 3: Number line and grid, including fractions and equivalents.
If the grid is set to auto, the numerator changes
