Skip Counting

Joyful Mathematics 2 — Patterns Around Us / Fun with Numbers. Skip counting by 2s, 5s, and 10s appears on hundred charts and pattern strips in Patterns Around Us.

• To count forward by 2s, 5s, and 10s without counting every number.
• How skip counting helps in money, pairs, and groups.
• To find missing numbers in a skip-count pattern up to 100.

Verbal: Count aloud in jumps: ten, twenty, thirty… — each step adds one ten without counting every number.

Symbolic: By 10s: 10, 20, 30… Rule: n → n + 10. By 5s: 5, 10, 15… Rule: n → n + 5.

Level 1 — Count by 10s

10, 20, 30, 40, …, 100 — each step adds one ten.

Level 1 — Count by 5s

5, 10, 15, 20, …, 100 — useful for counting ₹5 coins.

Level 1 — Count by 2s

2, 4, 6, 8, … — counting pairs of socks or shoes.

Level 2 — Finding the rule

Look at the gap between numbers: 20, 30, 40 → add 10 each time.

Level 2 — Real life

• ₹10 notes: ₹10, ₹20, ₹30…
• Auto-rickshaw fare increasing by ₹5.

Skip count by 5s starting from 25. What are the next three numbers?

Step 1 — Start at 25
Step 2 — Add 5: 25 → 30 → 35 → 40
Step 3 — Next three after 25: 30, 35, 40
Answer: 30, 35, 40

• Count by 10s from 40 to 80.
• What number comes after 55 when counting by 5s?
• Fill: 12, 14, 16, __, __

Stretch: Auto fare is ₹10, ₹15, ₹20… What is the rule? What fare comes after ₹45?

Revision tip: Clap on every fifth count while counting ₹5 coins — your ears and hands learn the pattern together.
