The big picture
One rule, checked twice. That is every pattern here.
| Idea | Remember | Example |
|---|---|---|
| A pattern is a rule | It tells you what comes next. | beads, or 2, 4, 6 |
| Number sequences | Start at a number, add the same step. | ₹5, ₹10, ₹15 |
| Shape numbers | Some counts make a square, triangle, or rectangle. | 9 dots = 3 rows of 3 |
| Odd and even | Even pairs up fully. Odd leaves one dot over. | 3 + 5 = 8, even |
| Growing shapes | A shape grows by the same rule each step. | +4 tiles every step |
| Explaining why | Matching a few numbers is a start, not proof. | 5, 8, 11 fits two rules |
