Class 4 Maths Chapter 9, Equal Groups, uses jumping animals (frog jumping by 3s, squirrel by 4s, rabbit by 6s, kangaroo by 8s) and Gulabo’s garden to teach multiples, common multiples, doubling magic, multiplying by 10s and 100s, and division as equal sharing/grouping.
What Class 4 Mathematics Chapter 9 Covers
Animal Jumps, Multiples & Common Multiples tracks number-line jumps to discover multiples of 3, 4, 6, and 8, and identifies numbers where two animals land together (common multiples).
Doubling Magic, Multiplying by 10s/100s & Division Patterns builds multiplication tables using doubling (e.g., 2× → 4× → 8×) and splitting (partial products), multiplies by 10 and 100, and connects multiplication facts with division quotients and remainders.

FAQ
What are common multiples in the Animal Jumps activity?
When a rabbit jumps in steps of 6 (6, 12, 18, 24, 30, 36, 42, 48…) and a kangaroo jumps in steps of 8 (8, 16, 24, 32, 40, 48…), the numbers both land on — 24, 48, 72 — are common multiples of 6 and 8.
How does ‘The Doubling Magic’ help in multiplication?
If you know the 2-times table, doubling it gives the 4-times table, and doubling again gives the 8-times table (for example, 3 × 2 = 6, so 3 × 4 = 12 and 3 × 8 = 24).
