From scratch to new possibilities
Subzero temperatures, positions and variations help to expand what we know about natural people. We use ℤ = {…, −3, −2, −1, 0, 1, 2, 3, …}. Naturals, including zero, are part of integers.
Choose your track
| Trail | What to explore | First step |
|---|---|---|
| 🌱 Elementary I · 1st to 5th year | Concrete situations with zero, temperatures and measurements | Discover |
| 🚀 Elementary II · 6th to 9th grade | Line, comparison, opposites, module, operations and powers | Investigate |
| 🎓 High School · 1st to 3rd grade | Pascal, algebra, functions and graphs | Deep deeper |
The levels suggest a reading path. You can go back to review or move forward when be able to explain their strategies. Measurements, angles and functions are complementary connections to the study of integers.
How to study: imagine the situation, draw or explore the figure, explain your reasoning and check the answer.
