One lesson. One task. One whole class.

But every child understands the lesson in a different way.

Teachers notice the nuances. Still, with 26 children in the room, there is little opportunity to reach out to each one of them in time. Intreea shows who is struggling, what lies behind their mistakes and when they need support.

Where does the thread snap?

In a lesson with 26 children, one child's difficulty easily remains unseen. Intreea shows it while it is still manageable.

Everything you need in one lesson, for the whole class

  • Everyone gets their own version

    The same difficulty, different content. Copying stops making sense.

  • Coverage and mastery

    How much each student has covered, and how much they have understood.

    Mastery correct answers, goal 85%

School management monitors the whole process

Progress is shown by class, subject and section. You see where the school is doing well and where it needs support.

Classes are created by the school's administrator. The data stays with the school.

Why it works

Intreea is an original version of the Accelerated Learning methodology, adapted for a digital environment: neuroscience, neuropedagogy and game-based mechanics. The platform follows the curriculum and brings children back to topics already studied until they consolidate them.

Technology does not replace the teacher. It helps them. The lessons adapt to the student, not the other way round.
