Track quiz
A quick cheat-sheet first, then the quiz.
| Idea | Remember |
|---|---|
| A pattern is a rule | It tells you what comes next. |
| Number sequences | Start at a number, add the same step each time. |
| Shape numbers | Some counts make a square, triangle, or rectangle. Not every count does. |
| Odd and even | Even pairs up fully. Odd always leaves one dot over. |
| Growing shapes | A shape grows by the exact same rule every step. |
| Explaining why | Matching a few numbers isn't proof — rules can split apart later. |
You see 3, 6, 9, 12. What is the rule?
A sequence starts at 4 with a step of 5. What is its third number?
Can every count of dots make a neat square?
A triangle of dots has rows of 1, then 2, then 3. Which count fills it exactly?
You add 6 + 9. What kind of answer should you expect?
A plus-shaped pattern starts at 5 tiles. It adds 4 tiles every step. How many tiles at step 3?
Two different rules both match 5, 8, 11. What does that prove?
Chapter 1, Patterns in Mathematics, opens your whole NCERT year. Read it slowly — you already know most of it.
Next: Lines and Angles — points, rays, and what an angle really measures.
