This activity aims to teach fractions and make the kid works on both numerator and denominator.
- User needs to create the denominator first by clicking on a button which adds rows and columns.
- After representing the denominator, user needs to select a part of them to represent the numerator.
- Then using an OK button to verify his answer.
Example:
If the displayed fraction is 1/2, at initial view shows a full rectangle:
- User needs to click on the "add one part" button. The original rectangle will be shared in two parts representing the denominator.
- Then the user can select 1 part of the two, (changing the color of the selected part), to represent the numerator.
An additional button allowing to share all the parts in two (1/2 becomes 1/4; 1/8 becomes 1/16) allows pupils to represent all the denominators part more quickly
there should be an additional button to add a "unit rectangle" if the number to represent is more than 1
