An adventure that starts with counting
How many toys are in the box? How to split a collection? What pattern appears in a sequence? Here, numbers gain meaning with everyday situations, figures you can explore and challenges. We use the convention ℕ = {0, 1, 2, 3, …}: zero is also a natural number.
Choose your track
| Trail | What will we discover | First step |
|---|---|---|
| 🌱 Elementary I · 1st to 5th year | Counting, place value and the four operations | Start exploring |
| 🚀 Elementary II · 6th to 9th grade | Divisibility, primes, GCD, LMC and standards | Investigate the numbers |
| 🎓 High School · 1st to 3rd grade | Sequences, generalization and arithmetic progressions | Discover the formulas |
Your pace counts. The years indicate a suggested route. You can get back on track to review or move forward when you can explain how you solved the challenges.
How to enjoy every encounter
- Imagine: read the situation and try to predict the outcome.
- Explore: move the figure controls and observe what changes.
- Explain: tell us in your own words why the answer makes sense.
- Practice: solve the challenge before opening the answer; then try another round.
To study as a family or at school, set aside around 15 to 20 minutes per meeting. Use caps, paper and pencils to repeat off-screen what you discovered in the pictures.
