Q1.
The rabbit jumps 6 steps at a time. Which numbers will the rabbit touch? What is the smallest 3-digit number on which the rabbit will land? How many times did the rabbit jump to reach this number? These numbers are multiples of ___.
Answer
The rabbit’s path. It starts at 0 and lands on every sixth number.
The rabbit touches 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 … — it skip counts in 6s.
Near 100: 90, 96, 102 96 is less than 100 and 102 is more than 100. So the smallest 3-digit number the rabbit lands on is 102. 102 = 17 sixes, so the rabbit jumped 17 times.
These numbers are multiples of 6.
Why it happens: The rabbit can land only on numbers made of whole groups of 6. 100 is not made of whole 6s, so the rabbit steps over it to 102.
Q2.
The kangaroo jumps 8 steps at a time. Which numbers will the kangaroo touch? These numbers are multiples of ___. Are there numbers that both the rabbit and the kangaroo will touch?
Answer
The kangaroo’s path. It starts at 0 and lands on every eighth number.
The kangaroo touches 0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80 … — it skip counts in 8s.
Tip: These shared numbers are the common multiples of 6 and 8. They come after every 24 steps.
Q3.
To reach 48, how many times did the rabbit jump? _______ How many times did the Kangaroo jump to reach the same number? _______ What did you observe? Share your thoughts.
Answer
The rabbit’s path. It starts at 0 and lands on every sixth number.The kangaroo’s path. It starts at 0 and lands on every eighth number.
Rabbit jumps 6 at a time: 6, 12, 18, 24, 30, 36, 42, 48 48 = 8 sixes, so the rabbit jumped 8 times.
Kangaroo jumps 8 at a time: 8, 16, 24, 32, 40, 48 48 = 6 eights, so the kangaroo jumped 6 times.
What we observe: the bigger the jump, the fewer the jumps needed.
Why it happens: Both animals cover the same 48 steps. The rabbit uses 8 groups of 6 and the kangaroo uses 6 groups of 8 — and 8 × 6 and 6 × 8 are both 48.
