Skip-counting jumps

In your book, Maths Mela (Chapter 9), animals jump along number tracks, starting from 0. The frog jumps 3 steps at a time. It lands on 0, 3, 6, 9, 12, 15, 18 and so on. These numbers are called multiples of 3. Will the frog touch 67? After 22 jumps it is on 66, and the next jump takes it to 69. So it jumps right over 67: 67 is not a multiple of 3.

The squirrel jumps 4 steps at a time: 0, 4, 8, 12 … These are the multiples of 4. To reach 60 it needs 15 jumps, because 15 fours make 60.

The rabbit jumps 6 steps at a time: 0, 6, 12, 18 … the multiples of 6. What is the smallest 3-digit number it lands on? 16 jumps take it to 96, which has only 2 digits. One more jump, the 17th, takes it to 102. It never lands on 100.

The kangaroo jumps 8 steps at a time: 0, 8, 16, 24 … To reach 48, the rabbit needs 8 jumps of 6, but the kangaroo needs only 6 jumps of 8. To reach 60, the frog needs 20 jumps of 3 and the rabbit only 10 jumps of 6. The bigger the jump, the fewer jumps are needed.
