Description

This activity aims to teach fractions and make the kid works on both numerator and denominator.

  1. User needs to create the denominator first by clicking on a button which adds rows and columns.
  2. After representing the denominator, user needs to select a part of them to represent the numerator.
  3. Then using an OK button to verify his answer.

Example:
If the displayed fraction is 1/2, at initial view shows a full rectangle:

  1. User needs to click on the "add one part" button. The original rectangle will be shared in two parts representing the denominator.
  2. 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

Teaching fraction requires to work on both numerator and denominator. This is well explained here https://www.taalecole.ca/enseigner-fractions/ .
User needs to first create the denominateur. In class it is done using paper that we fold in equal part.
We could do the same on gcompris:


or with circles too as it is important to show different types of fractions to not create false types in children minds.
A button to add rows an other to add columns within a rectangle would do the job, a button to add a section in the circle too.
The fraction to represent should be presented in number not written with letters.
It would be great for older children to have factions greater than 1.

As it is a difficult exercice and the ability from GCompris to immediate correction would be a great advantage to teach this notion.
