This animation is a generator of random problems on fractions. It allows the teacher to reinforce the fundamental notions and the student to test his knowledge.

Both frames must represent the same number.

A fraction can be represented by:

- its literal expression (three quarters),
- its mathematical writing (3/4),
- a graph (portion of a bar or disk),
- part of a collection of objects.

Five types of questions randomly combine two representations of the same fraction. All possible combinations are proposed in order of increasing difficulty. The padlock allows to freeze a type of question.

Objects in a collection can be moved to make packages.

**Click** on the active areas to answer the questions. The two frames should represent the same number.\n**Move** items to form packages.\n**Click** the "Back to Zero" button for a new question.\n**Click** on the padlock to freeze a type of question.

- To be able to represent simple fractions.
- To know how to write a fraction from its graphical representation and vice versa.
- To know how to solve problems.

The animation on fractions allows to introduce the fundamental notions.
