Jero, the Long-Eared Jerboa. GANCE's tutor.
Meet Jero

Big ears. He listens first.

Jero asks questions before he gives answers. Behind him, μikor checks what your child knows, picks the next step and decides which hint will help most.

Diagnose. Finds exactly what your child is ready for.
Choose. Every lesson uses the best of nine systems.
Explain. Adjusts the hint: a question, a picture or a worked example.
Pace. Notices repeated mistakes or long pauses and suggests a break.
Which piece of chocolate is bigger?
Jero
Take your time. Tap the one you think is bigger.
We check what your child remembers a week later, not only today.
Learn together

Any language, from age 2. Jero speaks with your child, and with you.

Family Language Night turns ten minutes after dinner into practice for everyone at the table. Jero runs the game, the grown-ups play too, and the evening digest suggests one thing to try at dinner tomorrow.

Ages 2 to 4: count with a grown-up

Jero sings a counting song while you and your child tap the ducks on screen: one, two, three. Naming objects around the house comes next. No reading needed.

From tonight's digest

Ask Maya to split a snack into equal parts and name the fractions out loud.

Tonight's word is manzana. Who can find something red on the table?

How do I say "two apples"?
Her dad
Jero
Dos manzanas. Now ask Sofía how many she wants.
Your language, your history

¡Hola! Soy Jero. ¿Contamos las estrellas juntos?
