Number Patterns

NCERT anchor: NCERT Joyful Mathematics Class 1 — Chapter 8: Fun with Numbers (+1 and +2 patterns)

• Continue +1 patterns: 2, 3, 4, 5…
• Continue +2 patterns: 2, 4, 6, 8…
• Use number line hops to verify the rule.

1. Add 1 each time

Level 1 (Verbal): Counting up by one — 7, 8, 9, 10.

Level 2 (Symbolic): Rule: +1 → next = previous + 1.

Visual: Hop one step right on number line each time.

2. Add 2 each time

Verbal: Skip one number — 3, 5, 7, 9 (odd numbers pattern).

Visual: Hop two steps on number line.

3. Find the rule first

Look at gap between numbers before continuing.

Cricket runs per over: +2 pattern

Step 1 — Overs show runs: 2, 4, 6, 8, ?
Step 2 — Gaps: +2 each time → rule is **add 2**.
Step 3 — 8 + 2 = **10** runs next over (if pattern holds).
Step 4 — Check on number line: hop by 2 from 8 → 10.
Answer: 10.

• Continue: 5, 6, 7, ?
• Continue: 10, 12, 14, ?
• What is the rule in 1, 2, 3, 4?
• Stretch: Pattern 1, 3, 5, 7 — what is the next number and the rule?

Revision tip: Write the +1 or +2 rule in margin before filling blanks.
