| Download Fractions desktop application (Windows 64bit) | Download Fractions source code (Lazarus/Free Pascal) |
Description: A mathematics game, intended for primary school pupils and concerning the addition of fractions: From the
fractions displayed in the grid, choose 2, 3 or 4 and add them in order to get a result of 1. But attention: You may not enter solutions as 1/5 + 4/5,
as the number of different denominators must be at least 2 or at least 3 (as selected in the Settings) menu.
To select a fraction, just click the corresponding square in the grid: The fraction chosen will be highlighted and added to the answer field; to remove it,
use the Undo button. If you click a square and nothing happens, it's because you clicked at a bad place; be sure to click the
square outside the fraction text!
The application has several options making the game easier or more difficult: Selection of the number of operands (2, 3 or 4), the number of different
denominators (2 or 3), allowing or not halfs and tenths, using colors to mark all squares with fractions that have the same denominator.
